DNA and RNA Flashcards
1
Q
What controls the cell cycle
A
Check points
2
Q
Folding into a double helix
A
polymerization
3
Q
Strand that RNA is transcribed from
A
template strand
4
Q
3’ to 5’ strand
A
template strand
5
Q
5’ to 3’ strand
A
RNA and coding strand
6
Q
When genetic material is not identical
A
Mutation
7
Q
What type of DNA does a prokaryote have
A
Circular DNA
8
Q
Where the DNA strands separate
A
DNA fork
9
Q
The middle of DNA where it gets transcribed
A
Replication bubble
10
Q
Replication in Prokaryotic
A
- RNA primer opens DNA
- Elongation by RNA
3 Helicase breaks hydrogen bonds - Replication fork opens
- leading strand replicates with the opening of the repliaction bubble
- Lagging strand moves in opposite direction and copies in sections

Phenotype
A
what the DNA sequence expresses
13
Q
Drivers of evolution
A
Mutation
14
Q
What does a mutation cause
A
changes in amino acid sequence
15
Q
Gene
A
basic physical and funcitional unit of heredity
