Vedclass · Answer

(B) In $DNA$ molecules, the nitrogenous bases follow specific base-pairing rules known as Chargaff's rules.Adenine $(A)$, which is a purine, always pairs with Thymine $(T)$, which is a pyrimidine, via two hydrogen bonds $(A=T)$.Guanine $(G)$, which is a purine, always pairs with Cytosine $(C)$, which is a pyrimidine, via three hydrogen bonds $(G \equiv C)$.Therefore, the correct base pairs are $A-T$ and $G-C$.

Which purine and pyrimidine bases are linked together by $H$-bonds in $DNA$?
