Cumulative Study Flashcards
1
Q
What are the differences between DNA and RNA?
A
- ribose instead of deoxyribose in RNA
- uracil replaces thymine in RNA, A=U
- RNA is mostly single stranded (tRNA has small areas that are double stranded)
- RNA is complementary to a DNA template
2
Q
In genetics, what is a promoter?
A
a region of DNA that initiates the transcription of a particular gene
3
Q
Where does the promoter bind to begin transcription?
A
the initiation site
4
Q
What is RNA polymerase responsible for?
A
producing the primary transcript RNA (RNAP constructs RNA chains using DNA genes as templates, a process called transcription)
5
Q
All RNA molecules begin with the codon ____.
A
AUG
6
Q
Each codon dictates a specific ____.
A
amino acid
7
Q
Describe the “initiation” phase of transcription.
A
