replikaatiokierroksen

Replikaatiokierroksen refers to the process by which a DNA molecule is copied during the cell division phase of the cell cycle. This process is essential for the growth and repair of tissues in multicellular organisms. The replikaatiokierroksen begins with the unwinding of the DNA double helix by an enzyme called helicase, which creates a replication fork. The two strands of the DNA then serve as templates for the synthesis of new complementary strands, catalyzed by the enzyme DNA polymerase. This results in the formation of two identical DNA molecules, each consisting of one original strand and one newly synthesized strand. The replikaatiokierroksen is a semi-conservative process, meaning that each daughter DNA molecule contains one strand from the original DNA molecule and one newly synthesized strand. This process ensures the faithful transmission of genetic information from one generation of cells to the next.
