Guida verificata passo dopo passo1
Understand that mitosis is a process of cell division that results in two genetically identical daughter cells.
During metaphase, chromosomes align at the cell's equatorial plane, preparing for separation.
Each chromosome consists of two sister chromatids, which are identical copies formed during DNA replication in the S phase of the cell cycle.
These sister chromatids are held together by a structure called the centromere.
Therefore, during metaphase, each chromosome is composed of two chromatids.
