Post-transcriptional Regulation
After the DNA is transcribed and mRNA is formed, there must be some sort of regulation on how much the mRNA is translated into proteins. Cells do this by modulating the capping, splicing, addition of a Poly(A) Tail, the sequence-specific nuclear export rates, and, in several contexts, sequestration of the RNA transcript. These processes occur in eukaryotes but not in prokaryotes. This modulation is a result of a protein or transcript that, in turn, is regulated and may have an affinity for certain sequences.

Famous quotes containing the word regulation:
“Lots of white people think black people are stupid. They are stupid themselves for thinking so, but regulation will not make them smarter.”
—Stephen Carter (b. 1954)
