Vedclass · Answer

(A) The hairpin structure in $RNA$ is formed by intramolecular base pairing,where a single strand folds back on itself. The loop at the end of the hairpin is a single-stranded region that does not participate in base pairing. While the sequence can vary,$Uracil$ $(U)$ is often found in these loops,but among the given options,$Adenine$ $(A)$ is frequently involved in structural motifs or specific binding sites within these loops. However,it is important to note that $Thymine$ $(T)$ is not present in $RNA$ as it is replaced by $Uracil$ $(U)$. Therefore,$Thymine$ is incorrect. Given the context of standard biological questions regarding $RNA$ structure,$Adenine$ is the most plausible answer among the choices provided.

Column-$I$	Column-$II$
$(a)$ $\phi \times 174$ bacteriophage	$(i)$ $48502 \ \text{b.p}$
$(b)$ Human (diploid)	$(ii)$ $5386$ bases
$(c)$ $E. coli$	$(iii)$ $6.6 \times 10^9 \ \text{b.p}$
$(d)$ $\lambda$-phage	$(iv)$ $4.6 \times 10^6 \ \text{b.p}$
