Question

What are the steps in gene expression?

Answer 1

Gene expression:

1. Gene expression is the activation or "turning on" of a gene that results in transcription and the production of mRNA and subsequently proteins.
2. Gene expression takes place primarily through six steps.

Steps in gene expression:

1. Chromosome changes: DNA unpacking takes place in chromosome changes.
2. Control of transcription - regulatory proteins and control sequences.
3. Control of RNA processing - addition of cap and tail, splicing, flow through nuclear envelope.
4. Breakdown of mRNA in cytoplasm.
5. Control of translation.
6. Control after translation.
