Comparing Mitosis and Meiosis

Slide 001


Memory Maker!

Mitosis

Makes my “toes”

Meiosis

Makes a new “me”

Slide 002


Overall goal!

Mitosis

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

(One cell divides once, resulting in two cells)

Meiosis

REPRODUCTIVE CELLS

(One cell divides twice, resulting in 4 cells)

Slide 002


Effect on DNA!

Meiosis

Amount of DNA is cut in ½.

(Ex: Original Cell = 46 Chromosomes

Daughter Cells = 23 Chromosomes)

Mitosis

Amount of DNA is the same.

(Ex: Original Cell = 46 Chromosomes

Daughter Cell = 46 Chromosomes)

Slide 002


Interphase – INCREASE!Grab 3 colors – don’t draw until Prophase!

Mitosis

Meiosis

BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES

Prophase – PAIRS!Grab 3 colors
