DNA is very long in relation to its diameter. If a strand of DNA is 0.1 mm in length, what is the ratio of length to diameter, or the axial ratio ?

A

5000

B

50000

C

10000

D

100000

Text Solution

Verified by Experts

The correct Answer is:
B
`0.1 m m=10^(5)n m, ` diameter of DNA`=2n m`.
Axial ratio `=1xx10^(5//2)=50,000" "(n m =` nanometer )
