(I)GCSE Topic 3.24 b) Mitosis 2



-For cells to be 'identical', the original cell has to copy its chromosomes
- Copying of Chromosomes = DNA Replication
=> each chromosome undergoes a copying process to form an identical copy of itself with the same genes and alleluias 
=> these two copies are held together by a structure around the center region - CENTRONERE
-While the chromosomes are in a copied pair = A Pair of Chromatids
- Process of DNA Replication takes place in the nucleus while the nucleus is still in tact 
=> INTERPHASE of the cell cycle
