Ch. 11

Here are some things to consider on reviewing for chapter 11

Control points for gene expression:
1. Transcriptional regulation of the synthesis of RNA transcripts by controlling initiation or termination.
2. RNA processing, or regulation through RNA splicing or alternative patterns of splicing
3. Transitional control of polypeptide synthesis.
4. Stability of mRNA, because mRNAs that persist in the cell have longer lasting effects than those that are degraded rapidly.
5. Posttranslational control, which includes a great variety of mechanisms that affect enzyme activity, activation, stability, and so on.
6. DNA rearrangement, in which gene expression changes depending on the position of DNA sequences in the genome.
