Term
| nucleotide excision repair |
|
Definition
(1) enzymes detect an irregularity and cut damaged strand
(2) enzyme excises nucleotides on damaged strand
(e) DNA polymerase fills in gaps in 5-3 direction
(4) DNA ligase links it together |

Term
|
Definition
• binds at replication fork
• breaks H-bonds between bases and opens double helix |
|
|
Term
|
Definition
• binds ahead of the replication fork
• breaks covalent bonds in DNA backbone to relive twisting forces cause by opening the helix |
|
|
Term
| single-strand binding protein |
|
Definition
• binds after replication fork
• prevents H-bonds between bases and stabilize single-stranded DNA |
