Final answer:
Post-transcriptional and post-translational regulations are essential in gene expression control.
Explanation:
Post-transcriptional regulation occurs after mRNA is transcribed but before translation begins, involving mRNA processing, transport, or ribosome binding at the cytoplasmic level.
Post-translational regulation involves the regulation of gene expression after translation, including protein modifications affecting stability and function.
Regulation of gene expression occurs at various levels like transcriptional, post-transcriptional, translational, and post-translational levels.
