- 9.2: DNA Replication
DNA replication: The double helix is un'zipped' and unwound, then each separated strand (turquoise) acts as a template for replicating a new partner strand (green). Nucleotides (bases) are matched to synthesize the new partner strands into two new double helices.
17 mar 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.
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.
DNA is a double helix structure comprised of nucleotides. A nucleotide, in turn, is made up of phosphate molecule, deoxyribose, and a nitrogenous base. Know the fundamental structure of DNA and the process of DNA replication in this tutorial.
1 cze 2020 · Learn how DNA replication occurs during cellular division, where two identical molecules of DNA are created from a single molecule. Understand the structure, function, and process of DNA replication, as well as the proteins and enzymes involved.
Learn how bacteria and eukaryotes replicate their DNA using four stages: initiation, unwinding, primer synthesis, and elongation. Explore the proteins and enzymes involved in each stage, such as DNA helicase, primase, and DNA polymerase.
