Gene expression in
eukaryotes is controlled by a
variety of mechanisms that range from those that prevent
transcription to those that prevent
expression after the
protein has been produced.
Full article >>>Stages of
gene expression that are regulated
Any step of
gene expression may be modulated, from the
DNA-
RNA transcription step to post-
translational
modification of a
protein. Following is a list of stages where
gene expression is regulated: ...

gene expression in the brain tell us about
human evolution?
I think we only compared the
liver, blood, and brain, and we chose
liver and blood because they were
organs and systems where there didn't seem to be many differences.
