Post-transcriptional regulation includes all of the following mechanisms EXCEPT:RNA interference - anti-mRNA sequences bind to m
RNA 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.
You can use refraction which is the bending of light through a transparent material. Also the freezing and boiling points of water. One last one is the Cartesian five experiment, this shows the density of water. Hope this helped.
