1.4.3. The replication fork
-
The replication fork is a structure that forms within the nucleus during DNA replication.
-
It is created by helicases, which break the hydrogen bonds holding the two DNA strands together.
-
The resulting structure has two branching "prongs", each one made up of a single strand of DNA.
-
These two strands serve as the template for the leading and lagging strands which will be created as DNA polymerase matches complementary nucleotide s to the templates.
-
The templates may be properly referred to as the leading strand template and the lagging strand template.
