4. Epigenetic, transcriptional, post-transcriptional, translational, and post-

translational levels.


Epigenetic regulation of gene expression is based on the availability of gene promoters and level of chromatin condensation. Transcriptional regulation is associated with the functioning of specific transcription factors. Translational regulation of gene expression is related to the activity of micro RNA while post-translational regulation is mediated by post-translational modifications of proteins.
