Post-transcriptional regulation includes all of the following mechanisms except: rna interference - anti-mrna sequences bind to mrna and inactivate itmrna processing to remove introns and splice together the required exonsmrna stability - length of time that mrna remains intactpresence of transcription activators or repressors

D) presence of transcription activators or repressors

Explanation:

The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.

For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
