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

Answer:

D) presence of transcription activators or repressors

Step-by-step 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.
