Transcription Flashcards
1
Q
What is the technical definition of gene expression?
A
The process by which the information in DNA is converted into a functional end-product (typically protein)
2
Q
“Gene expression can be regulated at any stage” - What stages are involved in DNA expression?
A
- DNA transcription
- RNA splicing
- mRNA translation
- Protein modification and turnover
3
Q
What are the three stages of Transcription?
A
- Initiation
- Elongation
- Termination
4
Q
By which orientation does RNA polymerase operate across DNA?
A
5’ to 3’ orientation (downstream)
5
Q
When speaking of initiation, what is a promoter?
A
A sequence of DNA which directs RNAP binding
6
Q
What part of RNAP is known for recognizing the Promoter?
A
The sigma factor
