WebWhen 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. The elucidation of the structure of the double helix ...

The enzymatic potential of … DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase. Primase catalyzes the synthesis of a short RNA (or DNA in some living organisms ) segment called a primer complementary to a ssDNA (single-stranded DNA) template. After this elongation, the RNA piece is removed … See more In bacteria, primase binds to the DNA helicase forming a complex called the primosome. Primase is activated by the helicase where it then synthesizes a short RNA primer approximately 11 ±1 nucleotides long, … See more There are two main types of primase: DnaG found in most bacteria, and the AEP (Archaeo-Eukaryote Primase) superfamily found in archaean … See more • Overview article on primase structure and function (1995) • DNA+Primase at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more The AEP family of primase-polymerases has diverse features beyond making only primers.

WebDNA replication is a highly coordinated process that is initiated at multiple replication origins in eukaryotes. These origins are bound by the origin recognition complex (ORC), which subsequently recruits the Mcm2-7 replicative helicase in a Cdt1/Cdc6-dependent manner. WebEnglish Page; 立教大学HPへ; 研究者情報トップページへ
