Define: Replication Fork |
The point at which two DNA strands are separated to allow replication to take place |
|
Semiconservative Replication |
Half of the parent DNA molecule is conserved in the daughter molecule, so one strand is conserved and one is newly synthesised |
|
DNA Dependent DNA Synthesis |
DNA synthesis that depends on a parent DNA molecule to act as a template |
|
Which enzyme family is required for DNA dependent DNA synthesis and in which direction is DNA synthesized? |
|
|
What is exonuclease activity and what are the two possible types? |
polymerase removes DNA already attached to the template
polymerase removes nucleotides it has just inserted (proofreading) |
|
Why do single strands need to be protected and what proteins perform this function? |
Singles strands are protected by single strand binding proteins to prevent
|
|
What are primers and what makes them? |
A RNA nucleotide sequence needed for DNA polymerase III to start DNA synthesis. It is made by primase, an RNA polymerase |
|
How does the priming process differ in eukaryotes? |
