If the total amount of adenine and thymine in a double- stranded DNA is 45%, the amount of guanine in this DNA will be

A

0.225

B

0.275

C

0.45

D

0.55

Text Solution

Verified by Experts

The correct Answer is:
B
Amount of adenine + Amount of thymine = 45%
Amount of guanine + Amount of cytosine = 100 – 45%
=55%
Amount of guanine = Amount of cytosine
`= (55)/(2)` 27.5 %
