What is DNA replication. When & where does the process occur. Learn how & why DNA is replicated. Also, learn the replication steps in order with a labeled diagram.
DNA replication is the process in which a cell makes an identical copy of its DNA. It is vital for cell growth, repair, and reproduction in organisms as it helps with the transmission of genetic information. The replication process follows several steps involving multiple proteins called replication enzymes and RNA, or ribonucleic acid. In ...
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.
The process of DNA replication comprises a set of carefully orchestrated sequence of events to duplicate the entire genetic content of a cell. The current article provides a short insight into the complex DNA replication steps.
In this article, we shall discuss the structure of DNA, the steps involved in DNA replication (initiation, elongation and termination) and the clinical consequences that can occur when this process goes wrong.
DNA Replication has three steps - Initiation, Elongation, and Termination. Multiple enzymes are used to complete this process quickly and efficiently.
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.
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.
Key points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New 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.
Preview. DNA replication is a highly complex process where replication occurs on both strands of DNA. On the leading strand of DNA, replication occurs uninterrupted, but on the lagging strand, replication is interrupted and results in the synthesis of Okazaki fragments that need to be joined.
