DNA replication begins at specific site termed as origin of replication, which has a specific sequence that can be recognized by initiator proteins called DnaA. They bind to the DNA molecule at the origin sites, thus flagging it for the docking of other proteins and enzymes essential for DNA replication.


DNA replication generally occurs by a bidirectional mechanism in which two replication forks form at an origin and move in opposite directions, with both template strands being copied at each fork. Synthesis of eukaryotic DNA in vivo is regulated by controlling the activity of the MCM helicases that initiate DNA replication at multiple origins spaced along chromosomal DNA.

Examples abound in the biological world; cells are a common example. However, replicators can also be developed in the electromechanical (or mechatronic) realm. This is of interest to researchers in … Replication then proceeds in both directions until the entire molecule is copied. Figure \(\PageIndex{5}\).

7.2.2 Explain the process of DNA replication in prokaryotes, including the role of enzymes (helicase, DNA polymerase, RNA primase and DNA ligase), Okazaki fragments and deoxynucleoside triphosphates. The first stage of DNA replication in prokaryotes is the uncoiling of the DNA double helix by the enzyme helicase.

In molecular biology, DNA replication is the primary stage of inheritance. Central dogma explains how the DNA makes its own copies through DNA replication, which then codes for the RNA in transcription and … What's the difference between Replication and Transcription? Cell division is essential for an organism to grow, but when a cell divides it must replicate the DNA in its genome so that the two daughter cells have the same genetic information as their parent. DNA provides a simple mechanism for replication… So, this is what the DNA replication is and this happens in our cells as cell division occurs eukaryotic cells.
