A segment of DNA has 120 adenine and 120 cytosine bases. The total number of nucleotides present in the segment is

A

120

B

240

C

60

D

480

Text Solution

Verified by Experts

The correct Answer is:
D
According to Chargaff's rule, molar amount of adenine is equal to that of thymine and cytosme equals to guanine, A + G = T + C. So, a segment of DNA with 120 adenine base and 120 cytosme base will have same number of each thymine and guanine base (as, A = T and C = G), i.e. 120 thymine bases, 120 guanine bases, thus a total of 480 nucleotides
