Comparing Mitosis and Meiosis (1) Comparing Mitosis and Meiosis Slide 001

Memory Maker! Mitosis Meiosis Makes my “toes” Makes a new “me” Slide 002

Overall goal! Mitosis Meiosis Produce identical cells with the same amount of DNA, to replace dying cells or allow growth. Meiosis Produce cells with ½ the original amount of DNA so that offspring can receive traits from each parent. Slide 002

Cells That it Occurs in! Mitosis BODY CELLS Meiosis REPRODUCTIVE CELLS (One cell divides once, resulting in two cells) Meiosis REPRODUCTIVE CELLS (One cell divides twice, resulting in 4 cells) Slide 002

Effect on DNA! Mitosis Meiosis Amount of DNA is cut in ½. Amount of DNA is the same. (Ex: Original Cell = 46 Chromosomes Daughter Cell = 46 Chromosomes) Meiosis Amount of DNA is cut in ½. (Ex: Original Cell = 46 Chromosomes Daughter Cells = 23 Chromosomes) Slide 002

Interphase – INCREASE! Grab 3 colors – don’t draw until Prophase! Mitosis Meiosis BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES Slide 002

Prophase – PAIRS! Grab 3 colors Mitosis Meiosis X X X X X X X X X X X X BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES Slide 002

Metaphase - MIDDLE Mitosis Meiosis X X X X X X X X X X X X Slide 002

Anaphase - APART Mitosis Meiosis V V Slide 002

Telophase -TWO Mitosis Meiosis Slide 002

Cytokinesis - CUT Mitosis Meiosis Slide 002
