- DNA (ATGC) replicates so each chromosome becomes 2 chromatids held together.
- replication is to make an exact copy.
- chromatids split and move in opposite directions to form 2 identical daughter cells.
- mitosis brings about growth, reparation of tissue, occurs in any part of the body, and can be done by any cells (except sex cells).
- meiosis occurs only in sex cells.
- homologous chromosomes come together and then split in opposite directions to form 2 daughter cells.
- the 2 chromosomes in each chromosome of daughter cells split to form 2 cells, so a total of 4 new and non-identical cells are formed.
Diploid - double sets of chromosomes
Haploid - single set of chromosomes
