Strawberries have large genomes; they are
Every living thing has DNA — or deoxyribonucleic acid – which is a blueprint of what makes you a human, your dog an animal or your roses a type of flower. You may be surprised to learn that 60 percent of the DNA present in strawberries is also present in humans.
Each little piece of a living thing, known as a cell, has DNA in it. 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!
We specifically use fruits like strawberries and bananas because they are octoploid and triploid, respectively. This means that each strawberry cell has eight sets of DNA, and each banana cell has three sets, so there is a lot available for extraction.
Why use strawberries? Strawberries are octoploid, meaning that their cells each have eight duplicate copies of each chromosome. This gives the cells a lot of DNA, which means it is easier to extract a large amount of DNA that is visible to the naked eye.
Strawberries have large genomes; they are octoploid, which means they have eight of each type of chromosome in each cell. Thus, strawberries are an exceptional fruit to use in DNA extraction labs and strawberries yield more DNA than any other fruit (i.e. banana, kiwi, etc.).
Whereas most species, including humans, are diploid with two copies of the genome – one copy from each parent – strawberry is an octoploid, with eight complete copies of the genome that were contributed by multiple, distinct parental species.
1) Strawberries are soft and easy to pulverize or smash 2) Strawberries yield way more DNA than other fruits because they are octoploid, meaning that they have eight copies of each type of DNA chromosome. Other cells often contain one or two copies.
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. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.
The overlap exists because we all evolved from a common ancestor, a single-celled organism that lived three or four billion years ago, known as the last universal common ancestor (LUCA). Many of these common genes have been conserved through billions of years of evolution.
Thanks to the new gene, GM strawberries make a protein which helps them resist frost. They don't contain any other fish genes and, and do not taste or smell of fish.
Yes, in a multicellular organism (such as a human or a strawberry), all cells contain the same DNA.
Strawberry DNA will look like a stringy white substance since DNA molecules form long chains. As my kids put it, “it looks like snot!” But if you carefully stretch it out you can see more of the details of those strands of DNA.
Identical twins are the only siblings that share 100% of their DNA. Non-identical brothers and sisters share about 50% of inherited gene variants, which is why siblings and fraternal twins can be so different.
On average two siblings inherit 75% of their parent's DNA, three siblings inherit 87.5%, and |S| siblings inherit an average fraction of 1 – ½|S| of their parent's DNA.
More startling is an even newer discovery: we share 99% of our DNA with lettuce.
Here's what to include: apples, mango, orange juice, apricots, watermelon, papayas, mangos and leafy greens are all high in nutrients shown to protect DNA. Blueberries are especially powerful; in one study, 10.5 ounces significantly lessened damage to DNA, in only an hour.
? Kiwifruit can not only reduce DNA damage, but it also increases the repair rate of any DNA that has been damaged to get it back into shape.
We found that the raspberries produced the most DNA with an average of 0.21 grams, and bananas produced the least DNA with an average of 0.089 grams.
Kiwifruit are hexaploid (6 copies) and have 29 individual chromosomes.
While the cherry emoji somewhat leans towards the inexperienced (because `cherry' has been a term for `virginity'), strawberry is also used to denote sexual interest. But this one is a bit tricky because strawberry is also a symbol of someone who is promiscuous.
Why do we “crush” the kiwi/strawberry fruit? Crushing the kiwi/strawberry fruit physically breaks apart the cell walls.
What's more, bananas have three copies of each chromosome, just like other seedless plants. And for many genes, all three copies are different. The variety of banana used in the new study had just two of each chromosome, making it simpler than the Cavendish.
Boiling and Freezing the strawberries may have improved the yield of DNA in solution by helping break down the cell membrane allowing more DNA into solution.
Levi and Thomas (1999)developed an improved procedure for the extraction of high-quality DNA from a large sample of watermelon leaves. This technique is suitable for isolating high quality DNA used in RFLP and AFLP marker analysis employing restriction enzymes.
