Today we finished chapter 11 by discussing how micro RNA (miRNA) is used to block translation of mRNA, how transcriptional attenuation (premature termination of transcription) is prevented by the action of RNA binding proteins, and how riboswitches can act to prematurely terminate transcription or inhibit translation.
In chapter 12, we talked about the kinds of RNA that can be found in prokaryotes and eukaryotes, and what are their relative quantities, compared to other organic materials in the cell. Then we had an overview of how different kinds of RNA (tRNA, rRNA, mRNA) are processed.
