Question

In the presence of maltose; -Is level of cAMP high/low -CAP on/off? -Lac repressor on/off? -Will Transcription occur?
In the presense of glucose and lactose together; -Is the level of cAMP high/low? -CAP on/off? -Lac repressor on? -Will transcription occur?
Some explanation would be really much appreciated, thank you.

Explanation / Answer

When glucose and lactose both are present together;

1. level of cAMP is low

2. CAP is off. It is unable to bind to the site

3.Lac repressor on

4. Transcription is turned off because CAP cannot bind. When both glucose and lactose present repressor block transcription.
