What is the role of RNA polymerase in transcription?

Back

RNA polymerase synthesizes mRNA from the DNA template.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of making mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is an operon?

Back

An operon is a cluster of genes under the control of a single promoter, functioning together in a regulatory system.
