WebJun 22, 2024 · Replication of a cell’s DNA occurs before a cell prepares to undergo division—either mitosis or meiosis I. It takes place in three (ish) steps. DNA unwinds from the histones. An enzyme called DNA helicase opens up the helix structure on a segment of DNA, breaking the bonds between the nitrogenous bases.
