Mitosis and Meiosis

daughters split 2nd time into Haploid gametes

made up of DNA

DNA contains 4 bases, shortened to A, T, C & G

Stem cells have all their genes switched on

Mitosis

makes genetically identical cells (Clones) for reproduction/growth

cells dividing

Full number in humans of chromosomes in body cells is 46

Asexual reproduction involves mitosis

Meiosis

chromosome copied

cells split into 2 daughter cells

makes egg cells in the ovaries
