Molecular mechanism of DNA replication - Khan Academy
https://www.khanacademy.org/science/ap-biology/gene-expression-and-regulation/replication/a/molecular-mechanism-of-dna-replication
WEBSpecialized proteins recognize the origin, bind to this site, and open up the DNA. As the DNA opens, two Y-shaped structures called replication forks are formed, together making up what's called a replication bubble. The replication forks will move in opposite directions as replication proceeds.

WEBORIs are recognized by the replication machinery — specifically the pre-replication complex. A replication bubble is the region of DNA where new strands of DNA have been or are being synthesized. A replication fork is found at each end of a replication bubble.

WEBOct 31, 2023 · Eukaryotic chromosomes have multiple origins of replication, which initiate replication almost simultaneously. Each origin of replication forms a bubble of duplicated DNA on either side of the origin of replication.

WEBThe replication bubble is composed of two replication forks, each traveling in opposite directions along the DNA. The replication forks include all of the enzymes required for replication to occur - they are just not drawn explicitly in the figure so as to provide room to illustrate the relationships between the template and new DNA strands.

DNA Replication - The Definitive Guide | Biology Dictionary
https://biologydictionary.net/dna-replication/
WEBJun 1, 2020 · Definition. DNA replication is a process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA. As a semiconservative process, a single molecule containing two strands of DNA in double helix formation is separated, where each strand serves as …

DNA replication - Wikipedia
https://en.m.wikipedia.org/wiki/DNA_replication
WEBAs DNA synthesis continues, the original DNA strands continue to unwind on each side of the bubble, forming a replication fork with two prongs. In bacteria, which have a single origin of replication on their circular chromosome, this process creates a "theta structure" (resembling the Greek letter theta: θ). In contrast, eukaryotes have longer ...

WEBMar 17, 2022 · OpenStax. 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.

WEBIn one model, semiconservative replication, the two strands of the double helix separate during DNA replication, and each strand serves as a template from which the new complementary strand is copied; after replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand.
