WebChromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same … WebChromosomes don’t duplicate (replicate) during mitosis. They replicate in the S phase of the cell cycle, during interphase, about halfway between one mitosis and the next. To address your question, without a mitotic spindle, mitosis comes to a halt at metaphase and cannot proceed any farther.
WebThe first step in preparing for division is to replicate the cell’s DNA in the S phase. In the G2 phase, the centrosome replicates. In early M phase, the centrosomes move away from each other toward the poles of the cell, in the process organizing the formation of the mitotic spindle. ... * Chromosomes replicate before cell division ...
