Gene expression is

A

a regulated process that involves controlling the amount of proteins produced by a gene.

B

a random process that involves the coupling of collected mutated chromosomes in a gene.

C

a semi-regulated process that involves the combination of male and female genes in sex cells.

D

an experimental process that involves creating new genes using lipids and water molecules.

The correct option is A) a regulated process that involves controlling the amount of proteins produced by a gene.

Explanation:

Gene expression can be described as a process in which certain mechanisms occur to increase, decrease or stop the production of proteins by a specific gene. Gene expression is also termed as gene regulation. This phenomenon is very important as an organism's body requires specific amounts of proteins. Higher or lower amounts can be toxic for the body. So to carefully control the production of a gene product, gene regulation or gene expression is necessary.
