DNA replication - Wikipedia
网页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 .
9.2: DNA Replication - Biology LibreTexts
网页2022年3月17日 · 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 - The Definitive Guide - Biology Dictionary
网页2020年6月1日 · 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 Mechanisms - Molecular Biology of the Cell
网页DNA replication takes place at a Y-shaped structure called a replication fork. A self-correcting DNA polymerase enzyme catalyzes nucleotide polymerization in a 5′-to-3′ direction, copying a DNA template strand with remarkable fidelity.
DNA Replication – Definition, Process, Steps, & Labeled Diagram
网页2023年2月17日 · 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.
