Dna replikasjon
WebDec 5, 2024 · DNA Replication. The process by which a DNA molecule makes its identical copies is referred to as 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.

WebReplikasjon av DNA er energisk svært dyrt. Hoved-enzymet av DNA-replikasjon er DNA-avhengig DNA-polymerase. DNA-replikasjon er ganske rask. Replikeringen av DNA fra E. coli med 4, 6 x 106 bp krever 19 minutter. På en gjennomsnittlig polymeriseringsgrad av baser er 2000 bp per sekund i hver retning.
