Question

Which of the following is true about RFLP? (multiple answer)

		the repeat strands are very short
		it analyzes only mitochondrial DNA
		it involves amplifying DNA
		restriction enzymes are used to cut the DNA at the ends of the repeat sites
		length polymorphism is used to distinguish between individuals
		none of the above is true

Answer 1

restriction enzymes are used to cut the DNA at the ends of the repeat sites ,

length polymorphism is used to distinguish between individuals are true about RFLP

In RFLP(Restriction Fragment Length Polymorphism) specific restriction enzymes are used to cut DNA of organism and separate these fragments on gel, depend upon presence of restriction sites in DNA it cut DNA accordingly and produce different site of fragments pattern. due to mutation there is change in this fragment pattern and we can detect it on gel.
