Term
What are the 5 levels of control in Eukaryotic Gene Expression?
Definition
transcriptional control, transport control, mRNA translational control, RNA degradation control, and protein degradation control
Term
What is transcriptional control?
Definition
It regulates whether or not a gene is transcribed and the rate at which transcripts are produced
Term
What happens when CI levels are high and CI binds to the Pr promoter? this happens during lysogeny
Definition
It blocks the expression of CRO
Term
Explain the SOS pathway.
Definition
rec A binds to the Lex A repressor so that SOS genes are able to be expressed so it can repair damage from UV light.
Term
When is the lytic cycle induced?
Definition
RecA cleaves CI repressor, and CRO is expressed, which allows the late genes to be expressed and this induces the lytic cycle.
