What is the length of human DNA containing `6.6 xx 10^(9)` bp ?

A

22 nm

B

0.22 mm

C

2.2 m

D

22 m

Text Solution

Verified by Experts

The correct Answer is:
c
The distance between 2 nucleotides / nitrogen bases is 3.4 A and human DNA containing `6.6 xx 10^(9)` bp multiplied by this distance gives a length of 2.2 meters.
