Transcription
Transcription (Transcription factors, RNA Polymerase,promoter)
post-transcriptional modification (hnRNA,Splicing)
Translation
Translation (Ribosome,tRNA)
post-translational modification (functional groups, peptides, structural changes)
gene regulation
epigenetic regulation (Hox genes, Genomic imprinting)
transcriptional regulation
post-transcriptional regulation (sequestration, alternative splicing,miRNA)
post-translational regulation (reversible,irrevesible)

Post-translational regulation refers to the control of the levels of active protein either by means of reversible events (Post-translational modifications, such as Phosphorylation or sequestration) or by means of irreversible events (proteolysis).
