Which enzyme causes the sequence of RNA bases to join together to form mRNA?

Which enzyme causes the sequence of RNA bases to join together to form mRNA?

• A. Transcription
• B. Translation
• C. mRNA
• D. RNA polymerase

Answer: (D)

RNA polymerase is the enzyme that links ribonucleotides to form the mRNA strand during transcription. It reads the DNA template and, in the 5' to 3' direction, adds complementary ribonucleotides, forming phosphodiester bonds to build the growing mRNA chain. In eukaryotes, RNA polymerase II carries out this task and mRNA undergoes processing afterward. Translation is the process of reading mRNA to synthesize protein at the ribosome, not the enzyme that makes the RNA. Transcription is the overall process, with RNA polymerase as the key catalyst.
