2
Q
Describe replication
A
Accurately replicated;
Template for synthesis via base pairing
3
Q
Describe protein synthesis
A
Transcription and translation;
mRNA are specified by seq of nucleotides on template DNA strand in transcription;
mRNA used as template in translation
4
Q
Describe mutation
A
Genetic variation
5
Q
Describe stable genetic information
A
Capable of self-repair; highly stable in struct’;
6
Q
Why is DNA highly stable?
A
Base pairs held by H bonds;
Hydrophobic interaction;
Stabilising double helix struct’;
Adj nucleotides are held by strong covalent phosphodiester bonds
