The enzyme responsible for the synthesis of mRNA is

Question

BlackTom AI · Accepted Answer

The prompt asks for the enzyme responsible for synthesizing mRNA, which is a fundamental transcription enzyme. 
Option 1: DNA polymerase. This enzyme copies DNA during replication and also participates in DNA repair, not in synthesizing RNA from a DNA template, so it does not make mRNA. 
Option 2: RNA ligase. RNA ligase joins RNA fragments, such as Okazaki fragments on the lagging strand, but it does not synthesize RNA polymers from a template. Therefore, it is not the enzyme for mRNA synthesis. 
Option 3: hexokinase. Hexokinase catalyzes the phosphorylation of glucose to glucose-6-phosphate in glycolysis and is unrelated to RNA transcription. Hence, it cannot be responsible for mRNA production. 
Option 4: RNA polymerase. This enzyme is responsible for transcription, moving along the DNA template to synthesize an RNA strand, including mRNA, using ribonucleotides. In bacteria, RNA polymerase transcribes all RNA types, while in eukaryotes, specific RNA polymerase II handles mRNA synthesis. This makes RNA polymerase the correct choice.
