1
New cards
Okazaki fragments
\- segments in the lagging strand that builds away from the replication fork.
2
New cards
Topoisomerase
\- relieves winding of the strand ahead of helicase.
3
New cards
Helicase
\- enzymes that untwist the double helix at the replication forks.
4
New cards
Semiconservative model
one parent strand and one daughter strand.
5
New cards
Ligase
fuses okazaki fragments together.
6
New cards
5→3-
general rule of how DNA builds from the 5 carbon strand to the 3 carbon.
7
New cards
DNA polymerase III
builds DNA by using primers to build off from.
8
New cards
DNA polymerase I
removes sections of RNA primer and replaces it with DNA nucleotides
9
New cards
nuclease
cuts out and replaces damaged stretches of DNA (part of base excision repair)
10
New cards
telomeres
buffers for extra nucleotides in order for DNA to not lose genes
11
New cards
chargaffs rules
[G]=[C] [A]=[T]
12
New cards
leading strand
new strand builds continuously, moving towards the replication fork
13
New cards
lagging strand
DNA polymerase builds away from replication fork, not built continuously
14
New cards
mismatch repair
repair enzymes correct errors in base pairing
15
New cards
primase
adds RNA primers
16
New cards
__single stranded binding protein__
bind to and stabilize single stranded DNA. keeps the DNA from coming together again
17
New cards
telomerase
extends telomeres
