|
What is DNA polymerase (III)?
|
Builds DNA by causing dnTB to do it.
|
|
|
What does a helicase enzyme do?
|
Unzips DNA by breaking hydrogen bonds.
(Occurs simultaneously at different sites) |
|
|
What is dnTP?
|
Deoxynucleoside triphosphate (nucleotide with three phosphate attached to it.)
|
|
|
What is 3' > 5'?
|
A leading strand.
|
|
|
What is 5' > 3'?
|
A lagging strand.
|
|
|
What are RNA primase?
|
Small nucleotide sequence that attaches to DNA. Seals the RNA primer to begin replication.
|
|
|
What is a Okazaki fragment?
|
Fills in the gaps in the lagging strand?
|
|
|
Are lagging strands continuous or discontinuous?
|
Discontinuous.
|
|
|
What are topoisomerase?
|
Messing with the histones proteins in preparation for DNA synthesis.
|
|
|
What is a replication fork?
|
A splitting pathway between two strands of DNA.
|
|
|
What is a replication bubble?
|
The gap between two strands of DNA when they split.
|
|
|
What are DNA ligase?
|
It ligates/seals the okazaki fragments in place.
|
|
|
What does DNA polymerase (I) do?
|
Removes primers from the strands.
|
|
|
What does it mean for DNA replication to be semi-conservative?
|
Only half of the DNA is replicated, so there will be a new strand and an old strand.
|
|
|
What are SSB?
|
Single stranded binding protein.
