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.
