Q. Consider the following statements: (A) During DNA fingerprinting, the bulk DNA is separated from repetitive DNA using density gradient centrifugation. (B) The bulk DNA forms the small peak while satellite DNA forms the major peak during separation of repetitive and bulk DNA. Select the correct option
A) A is true, B is false
B) Both A and B are true
C) A is false, B is true
D) Both A and B are false
Explanation
To separate the repetitive sequences from bulk genomic DNA, density gradient centrifugation technique is employed during DNA fingerprinting. It generates different peaks, out of which the major peak is formed by genomic DNA while the small peaks are formed by satellite DNA.
