At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the b… orchid massage kingstonWebThus, at the end of prophase, one can see the nucleus replaced by chromosomes and early mitotic apparatus spanning between the two centrosomes.
