- DNA replication
- semi-conservative replication
- half of the strands in each new DNA molecule are from the original DNA molecule
- 1. double helix unwinds
- 2. the H bonds are broken between complementary bases by DNA helicase
- 3. each strand acts as a template. free nucleotides pair with complementary bases
- 4. condensation reaction joins the nucleotides of nw strands together (catalysed by DNA polymerase)
- 5. new H bonds form between bases
- 4. condensation reaction joins the nucleotides of nw strands together (catalysed by DNA polymerase)
- 3. each strand acts as a template. free nucleotides pair with complementary bases
- 2. the H bonds are broken between complementary bases by DNA helicase
- each end of a DNA strand is slightly different in its structure. One end is called 3' and the other is 5'
- anti-parallel strands
- Meselon and Stahl provided evidence for semi-conservative replication
