In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part of biological inheritance .
DNA replication, or the copying of a cell's DNA, is no simple task! There are about 3 billion base pairs of DNA in your genome, all of which must be accurately copied when any one of your trillions of cells divides 1 . The basic mechanisms of DNA replication are similar across organisms.
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.
2 nov. 2023 · Learn how DNA replication produces two identical copies of DNA from one original molecule. Explore the enzymes, proteins, and steps involved in the process, as well as its applications and similarities and differences in prokaryotic and eukaryotic cells.
12 nov. 2021 · Learn how DNA replication occurs in three major steps: separation, priming, and assembly of the new strands. Find out how complementary base pairing ensures the accuracy and fidelity of the process.
1 juin 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.
Il y a 2 jours · Learn how cells copy their DNA using four stages: initiation, unwinding, primer synthesis, and elongation. Explore the proteins and enzymes involved in bacterial and eukaryotic DNA replication, and the challenges and discoveries in this field.
