Question

What are the differences in the specific regions of DNA sequence called during DNA finger printing?

• A. Non repetitive DNA
• B. Repetitive DNA
• C. Satellite DNA
• D. Histone DNA

Answer 1

Answer:

B. Repetitive DNA

• In DNA finger printing, the differences in the specific regions of the DNA sequence are called as Repetitive DNA.

• In this part, a small structure of the DNA is repeated many times.

• These repetitive structures can be separated from the bulk genomic DNA.

• This is done by observing the different peaks achieved by them during the density gradient centrifugation.
