|
DNA polymerase
|
Any of several enzymes that catalyze the synthesis of DNA from deoxyribonucleotides.
|
|
|
dNTP (deoxynucleoside triphosphate)
|
A monomer that is the essential building block for making a new strand of DNA.
|
|
|
primase
|
An RNA polymerase that synthesizes a short stretch of RNA that acts as a primer for DNA polymerase.
|
|
|
antiparallel
|
Parallel but oriented in opposite directions.
|
|
|
helicase
|
An enzyme that catalyzes the breaking of hydrogen bonds between nucleotides.
|
|
|
single-strand DNA-binding protein
|
A protein that binds to the DNA opened by helicase and prevents the strands from closing back together.
|
|
|
topoisomerase
|
An enzyme that cuts and rejoins the DNA downstream of the replication fork in DNA synthesis, removing twists in the strand.
|
|
|
leading strand
|
The strand of DNA that is synthesized in one continuous piece with nucleotides added to the 3-prime end of the growing molecule.
|
|
|
lagging strand
|
The strand of DNA that is synthesized discontinuously in a series of short pieces that are later joined together.
|
|
|
replication fork
|
The Y-shaped site at which a double-stranded molecule of DNA is separated into two single strands for replication.
|
|
|
DNA ligase
|
An enzyme that catalyzes the formation of a phosphodiester bond between the deoxyribonucleotides synthesized by DNA polymerase.
|
|
|
Okazaki fragment
|
A short fragment of DNA produced during DNA replication; a piece of the lagging strand.
