The correct option is B 5 By Chargaff's Rule, we know that in a DNA,
Purine = Pyrimidines
and talking about the DNA - most common B-DNA consist of 10 base pairs per turn of the helix which explains that 5 Purines and 5 Pyrimidines will be present per coil of a DNA.
So, the correct answer to the question is '5'.
