If a specific kind of protein is not continually used by a cell, the gene for that protein is

The gene for the protein is turned on and off at different times.

Explanation:

The turning on and off of the gene is described as gene regulation. This process is important because it enables the cells to react quickly to the changes in the environment.

Note that , this process mostly occur at transcription level during gene expression , and help in determining the amount of protein made by a gene.

airlines i think? or a cruise boat? does this work out for u? ?
