Recombinants or rec. proteins
Replication factor subunits and DNA replication proteins are found in DNA replication complexes like GINS, MCM,.. and replication initiators producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two strands, and each strand of the original DNA molecule gene serves as a template for the production of the complementary strand, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication of genes.
