Can someone explain how gene expression is controlled during transcription?

gene expression can be controlled at transcription by cis and trans acting factors.

Cis= Promotor, enhancer sequences

Trans= Protiens that bind promotors and prevent transcription (eg. HP1) or methylation/acetylation/ubiquitination/sumolation etc.

Your question is really BROAD... so it's difficult to answer... please let me know if this is sufficient?

Thats all I needed to know :D

Thought I had missed one of them, but I think I got them all. In my book they arent called cis/trans though, so that might be good to know for the exam xD

Thanks!!!
