What does gene expression control? a. the proteins that are made by the cell
b. the rate at which DNA replication occurs
c. the duration between cell cycles
d. the division of the cell nucleus

a

Explanation:

Control of gene expression ,

1)Transcriptional control : controls when and how often the gene is being transcribed.

2)Post-transcriptional control :

- RNA process control determines how often RNA is been processed.

- RNA transport and location control : selection of mRNA to be transported to  

   cytosol.

- mRNA degeneration control ; selection of which mRNA is getting         destabilized.

3)Translational control ; section of which mRNA is being translated.

4) Protein activity control / post-translational control ; regulation of proteins by activation , deactivation, degeneration, compartmentalization and modification of protein.

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.
