Which is the basis of genetic mapping of human genome as well as DNA fingerprinting?

Options

  1. APolymorphism in DNA sequence
  2. BSingle nucleotide polymorphism
  3. CPolymorphism in hnRNA sequence
  4. DPolymorphism in RNA sequence

Correct answer

A. Polymorphism in DNA sequence

Step-by-step solution

Allelic sequence variation is described as a DNA polymorphism if more than one variant (allele) at a locus occurs in the human population with a frequency greater than 0 . 01 . If an inheritable mutation is observed in a population at the high frequency it is referred to as DNA polymorphism. Polymorphism in DNA sequence is the basis of genetic mapping of human genome as well as of DNA fingerprinting.
