Question

In a dsDNA, having 500 N base , 20% are Adenine. How many hydrogen bonds will be there in the given DNA?​

Answer 1

Answer:

your answer is 650

Explanation:

from chargoff rule if there is 20% Adenine then there will be also 20 % Thymine

from chargoff rule there will be 30% Guanine and 30% Cytosine

so 20% of 500=100

30%of 500=150

So there is 100 Adenosine ,100 Thymine ,150 Guanine and 150 Cytosine

From chargoff rule Adenosine Bind with Thymine by Double H-bond and Cytosine bind with Guanine by

3 H-bond

So Total H-bond = 2×100+3×150

=200+450

=650
