How many replicated chromosomes does the cell contain ...

Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. 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… WebTo date, our understanding of the structure and the 3D spatial organization of chromosomes at the prophase stage of the cell cycle remains sparse, as imaging is technically difficult without compromising the 3D structural integrity of the cell.
