Helicases
Proteins that unwind the DNA double helix.
Hemimethylation

Helicase
: An enzyme that unwinds the double DNA helix near the replication fork before
DNA polymerase
acts on it. Replication fork moves from 3' to 5' of the leading strand. Unwinding is also necessary for
DNA repair
.

A helicase, which unwinds the DNA ahead of the fork.
A primase, which generates an RNA primer to be used in DNA replication.
A DNA holoenzyme, which is actually a complex of enzymes that performs the actual replication.

The trimer, via its helicase activity, translocates on the DNA.
At a damage site, recognized by the uvrB protein, uvrA subunits dissociate.
The uvrC protein is recruited. Each uvrB and uvrC make endonucleolytic cuts.
