Nov 2, 2023 · DNA replication is the process of producing two identical copies of DNA from one original DNA molecule. DNA is made up of millions of nucleotides, which are composed of deoxyribose sugar, with phosphate and a base.
In molecular biology, [1][2][3] DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. [4] . DNA replication occurs in all living organisms acting as the most essential part of biological inheritance.
In the process of DNA replication, the DNA makes multiple copies of itself. It is a biological polymerisation, which proceeds in the sequence of initiation, elongation, and termination. It is an enzyme-catalysed reaction. DNA Polymerase is the main enzyme in the replication process. Following are the important steps involved in DNA replication:
Feb 17, 2023 · DNA replication is the process through which a cell’s DNA forms two exact copies of itself. It occurs in all living organisms as it forms the basis of inheritance in all living organisms. The enzyme carrying out transcription is called DNA polymerase. The primary mechanism of DNA replication is similar across all organisms.
Mar 17, 2022 · When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.
Jun 2, 2024 · Initiation, elongation and termination are three main steps in DNA replication. Let us now look into more detail of each of them: The point at which the replication begins is known as the Origin of Replication (oriC). Helicase brings about the procedure of strand separation, which leads to the formation of the replication fork.

Jun 19, 2018 · The biological process of making a new DNA or DNA strand is referred to as “replication”. DNA synthesis – making a new DNA, is an enzyme governed catalytic reaction involving DNA polymerase, ligase, helicase, topoisomerase, etc. DNA polymerase has a significant role in synthesizing new DNA by incorporating dNTPs into the growing strand.
Jun 1, 2020 · DNA replication is a highly regulated molecular process where a single molecule of DNA is duplicated to result in two identical DNA molecules. As a semiconservative process, the double helix is broken down into two strands, where each strand serves as the template for the newly synthesized strand by matching complementary bases.
All organisms must duplicate their DNA with extraordinary accuracy before each cell division. In this section, we explore how an elaborate “replication machine” achieves this accuracy, while duplicating DNA at rates as high as 1000 nucleotides per second.
