DNA organisation, nucleotide pairing and semi-conservative replication

What this note covers

1. DNA is packaged at several biological scales
2. A nucleotide sequence has chemical direction and complementary pairing
3. Replication is semi-conservative and template directed
4. Classic isotope evidence distinguishes replication models
5. Replication errors and damage can change sequence
6. Evaluate DNA evidence with scale, controls and uncertainty
