Question

Q.n.5) In "Extraction of DNA from Straberries, and precipitation of DNA", Write a short description of the DNA.

Answer 1

About DNA (deoxyribonucleic acid) :

                             All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how to develop and function, and is so important that this complex compound is found in virtually every one of its cells.

                                   Whether a human, rat, tomato or bacterium, each of its cells will have DNA inside of it . Each cell has an entire copy of the same set of instructions, and this set is called the genome. Scientists study DNA for many reasons: They can use DNA to make new medicines or genetically modify crops to be resistant to insects. They can solve who is a suspect of a crime.

Extraction of DNA from Straberries:

                                   During a DNA extraction, When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump. Then alcohol added to the solution causes the DNA to precipitate out. In this activity, strawberries will be used because each strawberry cell has eight copies of the genome, giving them a lot of DNA per cell
