Extra Bacteria Stff Flashcards
1
Q
When is the lac operon expressed?
A
Only when lactose is present and glucose is absent (bacteria prefer glucose as energy)
2
Q
What does CAP stand for in prokaryote gene regulation?
A
Catabolise activator protein
3
Q
What does CAP do?
A
Acts as a glucose sensor to activate transcription of the operon when GLUCOSE levels are low.
4
Q
What does bacteria primarily eat?
A
Glucose, but it will consume lactose if no glucose is available
5
Q
What are the two conditions the lac operon will be expressed?
A
Lactose is available
Glucose is not available
6
Q
What are the three genes of the lac operon?
A
Lac z
Lac y
Lac A
