Polyploidy, a condition more common in plants, occurs when multiple pairs of chromosomes are present in the genetic component of an organism. Kiwifruit contains 18 times more Vitamin K than Strawberry. Create the DNA Extraction Liquid. Fluid will slowly drip into the beaker, but this step takes a while. They just have a ridiculous amount of DNA/cell and so makes the type of extraction typically done in lower level labs easy to. We came up with the hypothesis that the strawberry will have more DNA tyhan the banana because the strawberries have more seeds than the banana and it produces more quantity. Kiwis and bananas both together produced the same amount of strawberries alone. Strawberry plant species have varying numbers of chromosomes (see the Strawberry Plant page for introductory information). The genetics of most things are relatively complex, but the genetics of strawberry plants throw an additional twist into the mix. The DNA in raw wheat germ is encased in the nucleus of the cell, and warm water (between 55 and 60 degrees Celsius) will deactivate a DNA-breaking enzyme in the cell. So in this episode, we're going to talk a little bit about the what, why, and how. We used Bananas, raw and Strawberries, raw types in this comparison. • Use Ziploc TM freezer bags rather than sandwich bags, as they are thicker. This is to break up some of the cells and provide a large surface area over which to extract the DNA. Re: DNA extraction. In one cup mix 60mL (1/4 cup) of water (room temperature) with 1 tablespoon of dish detergent soap and 1 teaspoon of salt. Our project is about finding out which fruit has more DNA, the banana or strawberry. 2 - Put the chunks in a jar and mash the kiwi as much as you can. What has more DNA banana or strawberry? How to do the experiment: 1 - Peel the kiwi fruit and chop it into small chunks. . Science&EnhancedScope&andSequence&-&LifeScience& Virginia'Department'of'Education'©'2012'' ' 4' Strawberry'DNAExtraction'Lab' Strawberry contains less Sugar. Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. Hypothesis. The result was that, in the case of the kiwis and strawberries, ripe fruit did in fact yield more extractable DNA. • Use non-iodized table salt or laboratory-grade sodium chloride. Gently mix (you don't want to form bubbles). banana, kiwi, etc.). white and opaque. (Remove the skin of the bananas and kiwi, we just want the insides!) Answer: You can extract DNA from jusr about anything. We plan to use detergent, salt, water, alcohol to extract and isolate the dna. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate. Kiwifruit contains 40.3µg of Vitamin K, while Strawberry contains 2.2µg. Make sure everything has been crushed and there is no chunks left. You'd never guess just from looking at them, but potatoes can have four sets of chromosomes. Strawberries are 8n. the sample will look like if DNA is extracted and isolated from the sample while the negative control lacks DNA. Plus, strawberries have eight copies of each chromosome (they're octoploid), so there's plenty of DNA to isolate. The long, thick fibers of DNA store the information for the functioning of the chemistry of life. (Remove the skin of the bananas and kiwi, we just want the insides!) Kiwifruit is richer in Vitamin C, Vitamin K, Copper, and Vitamin E , yet Strawberry is richer in Manganese. Analysis: My averages of all three fruits range from a difference compared to the other fruit of 1.67, 0.33 and 2. Next open the bag and add 10 ml of extraction buffer. DNA can be isolated and extracted from other foods such as meats, other produce, and even processed foods Do we absorb DNA from food? The outcome showed me that over ripe kiwis and strawberries produce more measurable DNA. Gently add 50 milliliters of shampoo. Why is strawberry DNA easier to extract then human DNA? We took samples of banana and starwberry and measured the DNA by millliters. Banana has 8 times more Vitamin B6 than Strawberry. Why is strawberry DNA easier to extract then human DNA? In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA (scientists call this octoploid). That means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see! His experiment involved bananas, kiwis, and strawberries. Strawberries yield more DNA than any other fruit because they have eight copies of each type of chromosome. That's known as 4n - n for "number of copies". That means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see! We came up with the hypothesis that the strawberry will have more DNA tyhan the banana because the strawberries have more seeds than the banana and it produces more quantity. banana, kiwi, etc.). Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. We have not actually performed the . Ripe strawberries are an excellent . 3. Best Answer. A. Then crush the strawberry into juice and pulp. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate. SUMMARY The objective behind Boyd's experiment was to find out whether ripe fruit would yield more extractable DNA than unripe or overripe. . Repeat theses steps with the banana. . Bananas or kiwi fruit can also be used but yield less DNA. A banana would. Plant geneticists from 14 different countries spent the last nine years mapping the genetic makeup of the tomato, and have discovered that the tomato contains 31,760 genes - that's 7,000 more genes than a human being! Ripe strawberries are an excellent . Mix one half teaspoon of salt, one third cup of water and one tablespoon of dishwashing liquid in a glass or small . Since DNA is a big component in reproduction, it makes sense that seeds should have lots of DNA relative to other parts of a plant like leaves and bark. Because the phosphorus group is more susceptible to change than in a strawberry DNA. Why do we use wheat germ to extract DNA? 5. Be sure to thaw the frozen berries at room temperature. Add 10 ml of the DNA extraction buffer and mash the strawberry and buffer for about one minute. Copy. Remove the greens from the strawberries and place two in a plastic bag and seal it tightly. Maybe especially in the food we eat. Fruit with flimsier or weaker cell walls and nuclear membranes will allow the DNA in the nucleus to come out more easily when placed under physical pressure, whereas it will be harder for . 4. Click to see full answer. Strawberry contains less Sugar. OBSERVE Why are strawberries used for DNA extraction? (You'll need it later.) Strawberry's daily need coverage for Vitamin C is 56% higher. Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. Then start mashing! Banana has 0.367mg of Vitamin B6, while Strawberry has 0.047mg. In an experiment I completed just a few days ago. The method of salting out is more effective than all the other methods of DNA extraction (Seeker et al., 2016 p135). Dip the glass rod or wooden stick into the tube where the strawberry extract and alcohol layers come into contact with each other. The tiny bits of wispy junk floating in the alcohol just above the boundary layer is DNA. Daily need coverage for Vitamin C from Kiwifruit is 38% higher. Daily need coverage for Vitamin C from Kiwifruit is 38% higher. Place a strawberry in a Ziploc bag and gently mash for two minutes, being careful not to pop the bag. Step 2: In a separate bowl, mix the washing up liquid, salt and tap water . In respect to this, why do strawberries have so much DNA? Place a funnel in a beaker and a coffee filter in the funnel. The sample for plants would be strawberries and the animal sample would be chicken liver. The experiment aimed at extracting DNA from kiwi fruit and strawberry fruit, and to compare the salting out approach to the YouTube method of extraction. To the best of my knowledge, fruits "yield" DNA more or less easily depending on the strength of their cell walls and nuclear membranes. Variables: The independent variable is strawberry and kiwifruit. . The DNA found in strawberry cells can be extracted using common, everyday materials. Click to see full answer. Because the phosphorus group is more susceptible to change than in a strawberry DNA. The under ripe does not produce very much enzymes so it yields less DNA. The experiment aimed at extracting DNA from kiwi fruit and strawberry fruit, and to compare the salting out approach to the YouTube method of extraction. Kiwifruit contains 18 times more Vitamin K than Strawberry. Seal the bag again and gently mix the strawberry juice with the . Kiwis can be 6n, and strawberries…. Strawberry contains less Sugar. In respect to this, why do strawberries have so much DNA? • Fresh or frozen strawberries can be used. While we are dioloid - 23 pairs of chromosomes - strawberries are octoploid meaning they have 8 copies of every gene. Create the DNA extraction buffer by mixing 450 milliliters of water with two teaspoons of salt. The dependent variable is the amount of DNA because it is measured. Strawberries are an exceptional fruit to use for this DNA extraction lesson because they yield more DNA than any other fruit (i.e. We took samples of banana and starwberry and measured the DNA by millliters. The method of salting out is more effective than all the other methods of DNA extraction (Seeker et al., 2016 p135). Ultimately, the results of agarose gel . His experiment involved bananas, kiwis, and strawberries. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate. Wiki User. Use a pipette to add 10 milliliters of the DNA extraction buffer to the bag and mash for one minute. Which has more DNA, plants or animals? Step 2: In a separate bowl, mix the washing up liquid, salt and tap water . The result was that, in the case of the kiwis and strawberries, ripe fruit did in fact yield more extractable DNA. The tomato genome has been decoded! The plan is to remove the dna from the container witha popsicle stick and weigh the dna on the stick. Food types used in this article are Kiwifruit, green, raw and Strawberries, raw. Carefully open the bag with your sample and pour it into the filter. However, DNA does more than specify the structure and function of living things it also serves as the primary unit of heredity in organisms of all types. Chill the rubbing alcohol in the freezer. SUMMARY The objective behind Boyd's experiment was to find out whether ripe fruit would yield more extractable DNA than unripe or overripe. Strawberry plants have a very unique diversity when it comes to their genetic makeup. More than a whole gram of DNA was able to be extracted from the Banana compared to a strawberry. You don't want the skin because it's mostly dead and doesn't have much DNA in it. Put the strawberry in the bag, squeeze out most of the air and seal the bag. Why? Strawberry species and hybrids can be diploid, tetraploid, pentaploid, hexaploid, heptaploid, octoploid, or decaploid (having 2, 4, 5, 6, 7, 8, or 10 sets of the seven strawberry chromosomes, respectively). Ultimately, the results of agarose gel . white and opaque. Our project is about finding out which fruit has more DNA, the banana or strawberry. The purpose of this experiment is to investigate which fruit (strawberry/kiwi fruit) has larger amounts of DNA and to extract and compare them to find out who has more. . The fluid in the beaker is called the . Kiwifruit contains 40.3µg of Vitamin K, while Strawberry contains 2.2µg. Foods like strawberries, bananas, kiwis, raspberries, and onions work particularly well in this lab. Bananas, kiwis and strawberries all work well. The polar/non-polar boundary layer causes the DNA to precipitate. So, if we look at your experiments, strawberries, green peas, and tomatoes contain seeds, but grass doesn't. This might explain why peas and strawberries had more DNA than grass. In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA (scientists call this octoploid). Preparation. I assume that the ripe and over ripe kiwis and strawberries produce more enzymes "pectinases" which help in breaking down cell walls making it easier to extract the DNA. There would be more DNA in a strawberry because strawberries are octoploids, they have 8 copies of genes rather than 2 copies found in a cheek cells . The total number of DNA for each fruit had a big variation between strawberries compared to kiwis and bananas with a difference of 5 and 6. Food Samples . What has more genes than humans? Strawberries are an exceptional fruit to use for this DNA extraction lesson because they yield more DNA than any other fruit (i.e. Bananas, kiwis and strawberries all work well. Foods like strawberries, bananas, kiwis, raspberries, and onions work particularly well in this lab.
