To synthesize RNA from a DNA template.

Front

Define 'gene expression'.

Back

The process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What is the function of the promoter region in DNA?

Back

It is the site where RNA polymerase binds to initiate transcription.

Front

What is an operon?

Back

A cluster of genes under the control of a single promoter, functioning together in a regulatory manner.
