Vedclass · Answer

(B) During transcription, the enzyme $RNA$ polymerase synthesizes $mRNA$ using the $DNA$ template strand.According to the principle of complementarity, the nitrogenous bases in the $mRNA$ are complementary to the template strand of $DNA$.In $DNA$, Adenine $(A)$ pairs with Thymine $(T)$, and Cytosine $(C)$ pairs with Guanine $(G)$.In $RNA$, Uracil $(U)$ replaces Thymine $(T)$.Therefore, the base pairing rule for transcription is:$A$ $(DNA) \rightarrow U$ $(mRNA)$$T$ $(DNA) \rightarrow A$ $(mRNA)$$C$ $(DNA) \rightarrow G$ $(mRNA)$$G$ $(DNA) \rightarrow C$ $(mRNA)$Given $DNA$ template strand: $3'-ATGCTTCCGAAT-5'$Applying the rule:$3'-A \rightarrow 5'-U$$3'-T \rightarrow 5'-A$$3'-G \rightarrow 5'-C$$3'-C \rightarrow 5'-G$$3'-T \rightarrow 5'-A$$3'-T \rightarrow 5'-A$$3'-C \rightarrow 5'-G$$3'-C \rightarrow 5'-G$$3'-G \rightarrow 5'-C$$3'-A \rightarrow 5'-U$$3'-A \rightarrow 5'-U$$3'-T \rightarrow 5'-A$Resulting $mRNA$ sequence: $5'-UACGAAGGCUUA-3'$.Thus, the correct option is $B$.

If the sequence of nucleotides in a template strand of $DNA$ is $3'-ATGCTTCCGAAT-5'$, write the sequence in the corresponding region of the transcribed $mRNA$.
