Eukaryotic transcription regulation Flashcards
1
Q
Why is gene regulation important?
A
Proteins control and carry out everything
Euk have a large genome, cells differentiate to different functions but not all expressed
2
Q
What controls transcription?
A
regulatory sequence on DNA TATA box promoter gene regulatory protein Transcription factors RNA POL II
3
Q
Describe regulation in chromatin
A
Open chromatin is expressed.
Histone tails can be acetylated = loose
or methylated - condence
4
Q
When is loop in cell expressed?
A
when it is in expressed region not silence region
5
Q
What is TATA box?
A
it is involved in binding POL and promotion of transcription.
