A replication fork is then formed. In order to fit within a cell’s nucleus, dna is packed into tightly coiled. This process is performed at the beginning of every cell division so that when the. Dna replication is the process by which dna makes a copy of itself during cell division. In this article, we shall look briefly at the structure of dna, at the precise steps involved in replicating dna (initiation, elongation and termination), and the clinical consequences that can occur when this.
Dna Replication Process Steps. In eukaryotic cells, such as animal cells and plant cells, dna replication occurs in the s phase of interphase during the cell cycle. 1 st stage requires, there is no cdk activities. Dna replication is the biological process, in which cells create two identical copies of dna from the original dna molecule with high accuracy (fidelity rate). It is the basis for biological inheritance.
