Cell Division


Cell Division

Diploid – a cell with a full set of chromosomes

Haploid – a cell with half as many chromosomes

Chromatin – chromosomes wrapped around proteins called histones.

Cell Cycle


•G1 phase – the cell grows (new organelles and proteins are made) in preparation for mitosis

•S phase – DNA synthesis (by semi-conservative replication); ready to divide by mitosis

•G2 phase – the cells continue to grow in preparation, e.g. protein synthesis (proteins made needed for the division)

Mitosis the process by which cells undergo nuclear division (divide into two cells) to achieve growth and repair
