3.24b Mitosis 2

understand the division of a diploid cell by mitosis produces 2 cells which contain identical sets of chromosomes

-cell divides to form 2 cells and when you look inside the nuclei they will have the same number of chromosomes and the same number of sets.
-DNA replication- each chromosomes undergoes a copying process to form an identical copy of itself and is held by a structure called a centromere.
-they are now called a 'pair of chromatids'
-process of DNA replication takes place inside the nucleus while the nucleus is still intact, you cant see the process- it is called the interphase of the cell cycle.
