REGULATORY RNA/
PHAGE STRATEGIES
A. Controlling Gene Expression using Regulatory RNAs:
- Regulation by RNA uses
- RNA can shift between one structure and another =
- Changes in structure can be result
- Secondary structure changes occur
1. Intramolecular mechanisms of regulation
a. mRNA structure prevents translation
- Translational regulation of
- At one conformation of
mRNA,
- Second AUG may be
blocked because
- Ribosome movement
2
b. mRNA structure terminates transcription = Attenuation
- Controls the ability
