Answer:
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.
The optic nerve carries impulses to the thalamus and ultimately to the visual cortex of occipital lobes.
The optic nerve is a paired nerve, and part of the central nervous system that transfer visual messages from the retina to the vision areas of the brain through electrical impulses. The optic nerve is situated behind the eye and it is made up of retinal ganglion cell axons, glial cells and over one million nerve fibers.
