What is cell signaling? the process a cell goes through before it becomes functional nerve impulses that cause motion biochemical reactions that convey a message to a DNA promoter the process of protein catabolism

Solution

Cell signalling is the:

c, Biochemical reactions that convey a message to a DNA promoter.

This is a cascade of biochemical and molecular events, which involves processes like phosphorylation, dephosphorylation , etc, and apass the signalling process to turn on or turn off the transcription of specific genes.

So through cell signalling DNA promoter gets message to start or shut down a transcription process.
