1

Why do cells undergo mitosis and meiosis?

To creat identical daughter cells

2

Meiosis

The process of making egg and sperm cells

3

Mitosis

Distributes DNA to each new cell; identical daughter cell

4

Interphase

First
Normal cellular activity occurs, chromosomes are copied prior to prophase. DNA is in chromatin… Looks like spaghetti.
Duplicating

5

Prophase

Nuclear envelope begins to dissolve, leaving the double chromosomes bare. Each separate chromosome is now called a chromatid. These are attached to each other at the centromere.
(crossing over)

6

Metaphase

Chromosomes move to the middle

7

Anaphase

Chromosomes are split by spindles

8

Telophase

New cell wall (w/ plants)
New nuclear envelope

9

Mitosis: the number of chromosomes in the beginning cells and ending cells

Beginning: 46
End: 46

10

Meiosis: the number of chromosomes in the beginning cells and ending cells

Beginning: 46
End: 23

11

Each chromosome has....
(prophase)

Two chromatids

12

Cross over

Mom and dad chromosomes get tangled together, and trade equal sections of DNA

13

Prophase 2

No doubling the DNA but other than that the same is prophase 1

14

Mitosis number of divisions

2

15

Meiosis number of divisions

4

16

Zygote

A eukaryotic cell formed by a fertilization event between two gametes
