Question

during transcription, what enzyme is responsible for synthesizing mrna?

a. rna polymerase

b. trna

c. dna polymerase

d. rrna

Explanation:

To solve this, we analyze each option:

• Option a: RNA Polymerase is the enzyme that synthesizes mRNA during transcription by using DNA as a template.
• Option b: tRNA (transfer RNA) is involved in translation, carrying amino acids, not mRNA synthesis in transcription.
• Option c: DNA Polymerase is for DNA replication (synthesizing DNA), not mRNA synthesis in transcription.
• Option d: rRNA (ribosomal RNA) is a component of ribosomes, involved in translation, not mRNA synthesis.

Answer:

a. RNA Polymerase
