Q167 / 200 · NEET 2021 · Zoology

DNA fingerprinting involves identifying differences in some specific regions in DNA sequence, called as:

  • A
    Satellite DNA
  • Correct answer
    B
    Repetitive DNA
  • C
    Single nucleotides
  • D
    Polymorphic DNA

Solution

DNA fingerprinting is a very quick way to compare the DNA sequences of any two individuals. DNA fingerprinting involves identifying differences in some specific regions in a DNA sequence called repetitive DNA because, in these sequences, a small stretch of DNA is repeated many times.

Hence, the correct answer is option: 'B'.
