Answer:
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.
