A
- mitosis
- meiosis
3

Q
Semi- conservative replication process
A
- chains part
- breaking of hydrogen bonds
- by DNA helicase
- each chain acts as a template
- bases line up with complementary bases
- phosphodiester bonds join mononucleotides in condensation reactions
- by DNA polymerase

Q
What are the 5 requirements for semi- conservative replication?
A
- 4 types of nucleotides each with their bases
- both strands of DNA must act as a template
- enzyme DNA polymerase
- enzyme DNA helicase
- energy to drive the process
