Vedclass · Answer

(D) Statement $P$ is correct because $DNA$ contains the nitrogenous base thymine instead of uracil,which is found in $RNA$.Statement $Q$ is correct because $DNA$ follows Chargaff's rule,where adenine $(A)$ pairs with thymine $(T)$ via two hydrogen bonds.While both statements are scientifically accurate,statement $P$ (the absence of uracil) does not directly explain why $A-T$ pairing occurs (which is due to the specific chemical structure and hydrogen bonding capacity of these bases). Therefore,both statements are correct,but $P$ is not the explanation for $Q$.

Statement $P$: Uracil is not present in the structure of $DNA$.
Statement $Q$: $A-T$ complementary base pairing is present in the structure of $DNA$.
