1
Q
What are the forces stabilizing the Double helix of a DNA?
A
Hydrophobic Interaction, Van Der Waals forces and Hydrogen Bonds
2
Q
Melting temperature
A
50% of nitrogen bonds destroyed
Dependent on the length and composition of DNA
3
Q
Most Abundant Type of RNA
A
rRNA with 8% (1.5 % tRNA, 0.5% mRNA)
4
Q
Most Heterogenous Type of RNA
A
mRNA
5
Q
RNA usually found in Eukaryotes
A
sRNA
6
Q
Subtypes of sRNA
A
small nuclear RNA - gene regulation
micro RNA - inhibition of gene expression
small interfering - RNA regulation
7
Q
Prokaryotic Svedberg units
A
5s + 23s = 50s
16s = 30s
30s + 50s = 70s
8
Q
Eukaryotic Svedberg units
A
5s + 5.8s + 28s = 60s
18s = 40s
60s + 40s = 80s
