The expression of genetic information as protein is a complex process consisting of several steps. Genetic information is encoded in DNA that represents a linear sequence of nucleotides. The first step of the realization of genetic information is its storage and amplification that is controlled by replication. Replication is the process of the formation of two daughter DNA molecules based on the parent DNA molecule. Using special enzymes, the double helix of maternal DNA is decomposed into two strands, a second strand is built on each strand formed, producing two identical daughter DNA molecules, which are then twisted into separate spirals.
