There are two strands that are antiparallel; one runs in the $5' \rightarrow 3'$ direction and the other in the $3' \rightarrow 5'$ direction.

Vedclass · Answer

(D) According to the $Watson-Crick$ model of $DNA$ structure:$1$. $DNA$ consists of two polynucleotide chains that form a double helix.$2$. These two strands are antiparallel,meaning they run in opposite directions. One strand runs in the $5' \rightarrow 3'$ direction,while the other runs in the $3' \rightarrow 5'$ direction.$3$. According to $Chargaff's$ rule,the amount of adenine $(A)$ is equal to thymine $(T)$,and the amount of guanine $(G)$ is equal to cytosine $(C)$. Therefore,the total amount of purines $(A+G)$ equals the total amount of pyrimidines $(T+C)$.$4$. Option $D$ correctly describes the antiparallel nature of the $DNA$ strands.
