MITOSIS NOTES
• DNA is found in the nucleus of
• Chromatin –
• Chromosome – condensed DNA bound in the center by a
__________
Chromosomes
• How many chromosomes are on the left? How many on the right?
Mitosis
• Nucleus divides into 2 identical nuclei
• Product:
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
Cell Cycle
• Divided into 2 parts
– Interphase
– Mitosis
Interphase
•
• DNA
• Centrioles replicate and go to
Prophase
• Nuclear membrane
• Chromatin condenses to form
• Microtubules form spindle fibers, attach to
Metaphase
• Chromosomes line up on
Anaphase
• Chromatids pull apart at
• Cell begins to
Telophase
•
•
•
•
•
•
Opposite of
Cell starts to pinch at
Spindle fibers disappear
Chromosomes unwind to become
______ _______ forms in plant cells
Cytokinesis
• *Not part of mitosis
• Separation of
– Animals– Plants-
• FINAL PRODUCTS:

Closure
• How many chromosomes do you have in each cell?
• What phases are these cells in?
Asexual Reproduction
1. Binary Fission
– organism divides into
– Ex: bacteria, protozoan
2. Budding
– Parent divides into
– Ex: yeast, Hydra
3. Spores
– Thickly coated cells
– Ex:
4. Regeneration
– Ability to _________ lost body parts
– Ex:
5. Vegetative Propagation
– Using roots, stems, and leaves to make a new plant
Cancer
________ cell growth caused by
