The other, the … WebNew DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5' to 3' direction. During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging …

WebWhat is the first step of DNA replication? The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. WebThe first step of DNA replication occurs when a protein triggers the unwinding of the DNA helix. This is followed by a separation of the DNA strands prior to the transfer of genetic data to the newly assembled DNA strands.A protein known as helicase is responsible for breaking down the hydrogen bonds between strands of DNA during replication.

WebThis is the first step in the process of DNA replication. After the strands are split apart, RNA primers are added to the template strands. These primers give the DNA polymerase enzymes a place to start making new strands of DNA. The DNA polymerase enzymes then start making copies of the original DNA strands that are the same but not the same.
