Question

A 20 coil DNA has 480 H-bonds. Find out the number of guanine molecules in that DNA ?​

Answer 1

Answer:

70

Explanation:

It will depend on the Type of DNA i.e. A DNA, B DNA or Z DNA. They all have different number of base pair per turn. But as it is mentioned in the question that it is a typical DNA molecule, we can consider it to be B DNA. The range of number of Base pair is 10–10.5.

So,

If we take the Number of base pair per turn to be 10, Then the Answer will be 80.

If we take the Number of base per turn to be 10.5, Then the Answer will be 70.
