BACTERIAL OPERONS
A. General Considerations:
1. Early experiments with genetic regulatory circuits
a. Trans-acting products
- Can
- Can be
- Divided into:
i. Structural genes
- physical
- enzymes
ii. Regulatory genes
- products
b. Cis-acting sequences
- Not converted
- Function exclusively as DNA =
- Affect only
2. Simple regulatory circuits
a. Regulated by negative control
