Regulation of Genome Flashcards
(5 cards)
1
Q
What is signal transduction?
A
The mechanism through which a cell functions bye having transcription factors bind DNA and activate genes that will express effectors to carry out that function.
2
Q
Where in the process of expression of a gene can it be controlled?
A
- Transcription
- RNA processing
- RNA transport
- Translation
- mRNa degradation
- Protein activity
3
Q
What is the enhancer region?
A
The a cis acting region far upstream of transcription site where activator transcription factors bind to increase the expression of a gene.
4
Q
What are the activator proteins?
A
These are proteins that bind both the enhancer and RNA Polymerase II to form a DNA loop. Binding will recruit general transcription factors to form the transcription initiation complex.
5
Q
What are the silencer regions?
A
These are cis acting regions where repressor TFs will be recruited to.
