DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Step 1: The Separation of DNA Strands. The steps of DNA replication always begin by separating a twisted strand into two untwisted molecular strands. It happens in the specific area of a chromosome known as the âorigins. The origins contain a series of codes that attract the helicase, a protein that aids in the separation of the strands.
