The length of DNA molecile greatly exceeds the dimensions of the nucleus in eukaryotic cell. How is this DNA accommodated

A

Deletion of non-essential genes

B

Super-coiling in nucleosomes

C

D

Through elimination of repetitive DNA

Text Solution

Verified by Experts

The correct Answer is:
B
The length of DNA is 2.2 nm and we need to pack them as we have to transfer in next generation through sperm and ova. Thus, DNA being negative charge bind to positive charge histone proteins to form a thread like structure called chromatin material which further condenses to form chromosome.
