Replikaatiotapaan

Replikaatiotapaan, also known as replication fork, is a structure formed during the process of DNA replication. It is a temporary structure that forms when the DNA double helix unwinds and separates into two single strands. This separation is facilitated by enzymes called helicases, which break the hydrogen bonds between the base pairs of the DNA molecule.

The replication fork consists of two regions: the leading strand and the lagging strand. The leading strand is synthesized continuously in the 5' to 3' direction, while the lagging strand is synthesized discontinuously in short fragments called Okazaki fragments. These fragments are later joined together by an enzyme called DNA ligase.

The replication fork moves along the DNA molecule, synthesizing new complementary strands of DNA. This process ensures that each daughter DNA molecule is an exact copy of the original molecule. The replication fork is a crucial structure in the process of DNA replication, which is essential for cell division and growth.
