Alec Jeffreys used ________________ as genetic marker. A) HUMULIN B) Radioactive probe C) RFLP D) VNTR

Correct option:(D)VNTR

Solution:

  • Technique of isolating and sequencing the DNA is called DNA fingerprinting.
  • It was developed by Alec Jeffrey in 1984. Generally, a small amount of DNA is obtained from the samples.
  • PCR technique is used to amplify the DNA molecules present in a small sample in order to obtain a large amount of DNA sequence for the test.
  • It is followed by restriction fragment length polymorphism (RFLP).
  • RFLP analysis is used to identify the repeated sequences by detecting a specific sequence pattern to the Variable Number Tandem Repeats .
  • It becomes that individual’s DNA profile also called as genetic markers.
