Different efficiencies of translational initiation
o
Altered efficiencies of ribosome movement through the intergenic regions
between different ORFs on the same polycistronic (1 mRNA has more than
one effect) mRNA
o
Differential rates of degradation of specific regions of mRNA molecules
Post-translational regulation of gene expression – Feedback inhibition
o
Feedback inhibition occurs when the product of a
biosynthetic pathway inhibits the activity of the first enzyme
in the pathway, rapidly shutting off the synthesis of the
product
