Which enzyme is responsible for synthesizing messenger RNA from a DNA template strand during transcription in eukaryotes?

💡 Solution & Explanation

Eukaryotic RNA polymerase II is the specific nuclear enzyme responsible for transcribing all protein-coding genes to synthesize messenger RNA precursors. DNA polymerase III replicates genomic DNA, reverse transcriptase synthesizes DNA from RNA templates in retroviruses, and peptidyl transferase forms peptide bonds during ribosomal translation. Promoters and transcription factors guide RNA polymerase II to correct start sites on DNA templates.
