Vedclass · Answer

(A) According to the base pairing rules of $DNA$ (Chargaff's rules),$Adenine$ $(A)$ pairs with $Thymine$ $(T)$ and $Guanine$ $(G)$ pairs with $Cytosine$ $(C)$.Given the sequence: $GAT, TAG, CAT, GAC$.$1$. $G$ pairs with $C$,$A$ pairs with $T$,$T$ pairs with $A$. So,$GAT$ becomes $CTA$.$2$. $T$ pairs with $A$,$A$ pairs with $T$,$G$ pairs with $C$. So,$TAG$ becomes $ATC$.$3$. $C$ pairs with $G$,$A$ pairs with $T$,$T$ pairs with $A$. So,$CAT$ becomes $GTA$.$4$. $G$ pairs with $C$,$A$ pairs with $T$,$C$ pairs with $G$. So,$GAC$ becomes $CTG$.Therefore,the complementary sequence is $CTA, ATC, GTA, CTG$.

If the base sequence of one strand of $DNA$ is $GAT, TAG, CAT, GAC$,what would be the sequence of its complementary strand?
