DNA/RNA Flashcards
1
Q
Central dogma
A
DNA–>RNA–>protein
2
Q
Topoisomerase
A
Uncoiling the strands for replication
3
Q
What direction does DNA polymerase read?
A
3’ –> 5’
4
Q
How does RNA differ from DNA?
A
- Uses ribose (2’ OH)
- Contains Uracil instead of Thymine
- Usually single stranded
5
Q
Where is RNA found?
A
-Cytoplasm and nucleus
6
Q
Transcription
A
- Synthesis of mRNA
- RNA binds to promoter region
- Followed by post-transcriptional processing
7
Q
Translation
A
- mRNA codons translated into aa
- Initiation, Elongation, Translocation, Termination
8
Q
Parts of a Ribosome
A
- Two subunits
- A site (aminoacyl-tRNA complex)
- P site (peptidyl-tRNA)
- E site (exit)
