Phages
|
A parasitic virus in DNA
|
|
Double-Helix
|
A pair of parallel helices intertwined about a common axis, esp. that in the structure of the DNA molecule
|
|
Semiconservative model
|
Type of DNA replication in which the replicated double helix consists of one old strand, derived from the old molecule, and one newly made strand.
|
|
Origins of replication
|
a particular sequence in a genome at which replication is initiated
|
|
Replication Fork
|
The unwound region of the DNA double helix in which replication takes place
|
|
DNA Polymerase
|
the enzyme responsible for DNA replication
|
|
Leading Strand
|
During DNA replication, the strand that is synthesized in the 5′ to 3′ direction by continuous polymerization at the growing 3′ tip.
|
|
Lagging Strand
|
During DNA replication, the strand that is synthesized in the 3′ to 5′ direction by ligation of short DNA strands synthesized discontinuously in the 5′ to 3′ direction.
|
|
DNA ligase
|
In recombinant DNA technology, an enzyme that seals together two DNA fragments from different sources to form a recombinant DNA molecule
|
|
Primer
|
Short stretch of RNA synthesized on a DNA template. It is required by DNA polymerases to start their DNA synthesis.
|
|
Primase
|
DNA primase is an RNAP enzyme involved in the replication of DNA.
|
|
Helicase
|
A protein that unwinds DNA at replication forks.
|
|
Mismatch Repair
|
A system for recognizing and repairing erroneous insertion, deletion and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.
|
|
Nuclease
|
An enzyme that cleaves the chains of nucleotides in nucleic acids into smaller units
|
|
Excision Repair
|
Repair of damaged DNA by removal of the damaged segment of DNA and its replacement with a newly synthesized correct segment.
