Vedclass · Answer

(A) By analyzing the chemical structures of the nitrogenous bases:$1$. Structure $(P)$ is a pyrimidine with two carbonyl groups and no methyl group,which is Uracil.$2$. Structure $(Q)$ is a purine with an amino group at position $6$,which is Adenine.$3$. Structure $(R)$ is a pyrimidine with a methyl group at position $5$,which is Thymine ($5$-methyluracil).$4$. Structure $(S)$ is a purine with an amino group at position $2$ and a carbonyl group at position $6$,which is Guanine.$5$. Structure $(T)$ is a pyrimidine with an amino group at position $4$ and a carbonyl group at position $2$,which is Cytosine.Therefore,the correct identification is: $P$ = Uracil,$Q$ = Adenine,$R$ = Thymine,$S$ = Guanine,$T$ = Cytosine.
