Why must cytosine bind to guanine, while thymine bonds to adenine?

a
These are Chargaff's rules.
b
Like bonds with like.
c
Two-ring molecules (adenine and guanine) must bind with one-ring molecules (thymine and guanine) to keep the distance between DNA chains consistent.
d
This will not happen, as it violates Chargaff's rules.

Respuesta :

These are Chargaff's rules that is why cytosine bind to guanine, while thymine bonds to adenine. Thus, the correct option is A.

What is Chargaff's rule?

According to the rule, in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine).

According to Chargaff's rule, Concentration of adenine = concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.
