Final answer:
Post-translational control is a gene expression regulatory mechanism that occurs after translation, involving modifications to proteins affecting their function and stability.
Explanation:
Post-translational control is a regulatory mechanism of gene expression that occurs after translation. It involves modifications to proteins that can affect their stability and function.
Unlike other options like constitutive control, transcriptional control, and translational control, post-translational control acts on the already synthesized proteins rather than the gene expression process.
Examples of post-translational modifications include phosphorylation, glycosylation, and proteolytic cleavage which impact protein activity in the cell.
