Presentation transcript:

MITOSIS

WHAT PHASE IS SEEN HERE?

TELOPHASE

Chromatin condenses into chromosomes; nuclear membrane breaks down

PROPHASE

WHAT PHASE IS SEEN HERE?

METAPHASE

Sister chromatids separate and move to opposite poles.

ANAPHASE

WHAT PHASE IS SEEN HERE?

PROPHASE

Chromosomes line up in the middle; spindle fibers connect to centromere.

METAPHASE

WHAT PHASE IS SEEN HERE?

ANAPHASE

Chromosomes gather at opposite ends of the cell and two new nuclear membranes form. 

TELOPHASE

(Make sure to include I or II in your answer!) MEIOSIS (Make sure to include I or II in your answer!)

Spindle fibers pull homologous chromosomes towards opposite ends of the cell.

ANAPHASE I

WHAT PHASE IS SEEN HERE?

METAPHASE II

Spindle fibers separate chromosomes; chromatids are pulled to opposite side.

ANAPHASE II

WHAT PHASE IS SEEN HERE?

PROPHASE I

WHAT PHASE IS SEEN HERE?

ANAPHASE I

Chromosomes are randomly arranged; nuclear membrane begins to disappear. Centrioles and spindle fibers appear.

PROPHASE I

Homologous chromosomes line up in the middle of the cell

METAPHASE I

WHAT PHASE IS SEEN HERE?

TELOPHASE I

Crossing over occurs

PROPHASE I

WHAT PHASE IS SEEN HERE?

METAPHASE I

Two nuclear membranes form. The cell begins to separate into two cells.

TELOPHASE I

WHAT PHASE IS SEEN HERE?

ANAPHASE II

Four nuclear membranes form. Four non identical cells begin to separate.

TELOPHASE II

WHAT PHASE IS SEEN HERE?

TELOPHASE II
