How is the regulation of cell activity at the level of the transcription process?

I – pre-transcriptional (DNA methylation) – cell cycle; chromatin spiralization in eukaryotes
II-transcriptional:
a) initiation (promoters + regulatory proteins) b) termination (attenuation and antiterms and nation)
III – post-transcriptional:
a) mRNA stability (rpoS)
b) broadcast initiation (cold shock)
IV – post-translational; regulation of metabolism through protein-protein interactions and protein modification; allosteric regulation (chemotaxis).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
