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
WEBKey points: 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.

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.

Replication - Definition and Examples - Biology Online Dictionary
https://www.biologyonline.com/dictionary/replication
WEBJun 16, 2022 · Replication, in the general sense, is to create a copy or a duplicate. Thus, in biology, replication is commonly associated with DNA (DNA replication) where the DNA is copied prior to cell division. Apart from that, replication also refers to the duplication of a laboratory or experimental procedure, which is essential for research statistics.

DNA Replication Mechanisms - Molecular Biology of the Cell
https://www.ncbi.nlm.nih.gov/books/NBK26850/
WEBAll organisms must duplicate their DNA with extraordinary accuracy before each cell division. In this section, we explore how an elaborate “replication machine” achieves this accuracy, while duplicating DNA at rates as high as 1000 nucleotides per second. Go to: Base-Pairing Underlies DNA Replication and DNA Repair.
