(A) $1$. In the process of protein synthesis,$mRNA$ (messenger $RNA$) acts as the direct template that carries the genetic code for translation into amino acids.$2$. The sugar component of $RNA$ nucleotides is ribose,which contains a hydroxyl group $(-OH)$ at the $2'$ position of the sugar ring.$3$. In contrast,$DNA$ contains deoxyribose sugar,which lacks the $2'-OH$ group (it has only a hydrogen atom at the $2'$ position).$4$. Therefore,$P$ is $RNA$ and $Q$ is $RNA$.
