L. Regulation Of Protein Synthesis Flashcards
LAC in, LAC operon stands for
Lactose
Operon
Cluster of genes
The regulatory genes consist of
Promoter region
Operator region
Operator region
On/off
RNA polymerase:
What does it do?
Where is it found?
Performs transcription
Produce mRNA
In the promotor region
Repressor protein:
What does it do?
Where is it found?
Allosteric protein - accepts glucose and lactose
Operator region
Repressor protein:
Lactose
Inducer
Repressor protein:
Glucose
Corepressor (off)
When the Repressor protein has glucose in its active site
Able to bind to the operator
When the Repressor protein has lactose in its allosteric site
Unable to bind to operator
Beta-galactidase
Enzyme produce by structural genes of the LAC operon
Breaks the bond between glucose and galactose in lactose
Lactose is a
Disaccharide
