Vedclass · Answer

(D) In nucleic acids,the nitrogenous bases are classified into two types based on their structure:$1$. $	ext{Purines}$ (bicyclic bases with two fused rings): Adenine $(A)$ and Guanine $(G)$.$2$. $	ext{Pyrimidines}$ (monocyclic bases with one ring): Cytosine $(C)$,Thymine $(T)$,and Uracil $(U)$.Since Guanine $(G)$ is a purine,it possesses a bicyclic (double-ring) structure. Therefore,the correct answer is $G$.
