WebBiologie 5 Celvermeerdering 5.2 DNA replicatie. De DNA-replicatie vindt plaats voor de mitose in de S-fase van de interfase. In deze fase wordt de DNA-hoeveelheid verdubbeld en klaargemaakt voor de mitose. Het oorspronkelijke chromosoom en het nieuwgevormde chromosoom blijven nog op één plek, in het midden, aan elkaar vastzitten: het centromeer. WebHelicase opens up the DNA at the replication fork. Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. Topoisomerase works at the region ahead of the replication fork to prevent supercoiling. Primase synthesizes RNA primers complementary to the DNA strand. breech\\u0027s 0e https://caminorealrecoverycenter.com
