A) 80
B) 100
C) 120
D) 140
Correct Answer: D
Solution :
B-DNA shows 10 nucleotides per turn (coil) of helix, if there are 20 coils then total number of nucleotides is 200 out of which 120 are adenine (equal amount of thymine). So, the number of guanine (equal amount of cytosine) nucleotides is 80. Three hydrogen bonds are present between guanine and cytosine.You need to login to perform this action.
