DNA replication - Wikipedia
WEBIn 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 .
Molecular mechanism of DNA replication - Khan Academy
WEBDNA 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.
DNA Replikation • Ablauf, Enzyme, Eukaryoten und Prokaryoten
WEBDNA Replikation Definition. Die DNA Replikation (Reduplikation) (engl. dna replication) ist die identische Verdopplung des Erbguts (DNA). Sie wird in 3 Phasen (Initiation, Elongation und Termination) unterteilt und beginnt an einem definierten Startpunkt (Origin, Replikationsursprung).
9.2: DNA Replication - Biology LibreTexts
WEBMar 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.
DNA Replication: Enzymes, Mechanism, Steps, Applications
WEBNov 2, 2023 · DNA replication starts by taking one DNA molecule and giving two daughter molecules, with each newly synthesized molecule containing one new and one old strand. DNA replication simply is the process by which a DNA makes a copy of itself.
DNA Replication Steps and Process - ThoughtCo
WEBMay 2, 2024 · 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.

WEBDNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or...
DNA structure and replication review (article) | Khan Academy
WEBDNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).
