1) Interphase:
• Gap
1
: growing, carying out normal cell function.
• Synthesis: copies its DNA in preparation for cell division
• Gap
2:
Cell prepares for division of the nucleus
2) Nuclear division: Mitosis
3) Cytokinesis

Name and describe the 4 phases of mitosis ( in order)
Prophase:
• Nuclear membrane breaks down
• Nucleolus disappears
• Chromosomes coil and thicken
• Spindle begins to form between the centrioles

Metaphase:
• Chromosomes attach to the spindle and align along the equator of the cell.
Anaphase
• Microtubules shorten, moving chromosomes to opposite poles.

Telophase:
• Chromosomes reach poles of cell
• Nuclear envelope re-forms
• Nucleolus reappears
• Chromosomes decondense

• Sister chromatids are structures that contain identical copies of DNA and are attached together with a centromere

Cytokinesis: a process that divides the cytoplasm which results in two cells, each with identical nuclei.

• Centromere: joins the two sister chromatid
• Spindle: The apparatus that moves and organizes the chromosomes before cell division.
• Chromosome: A single copy of DNA
• Chromatin: All the chromosomes in a relaxed state (during interphase)
• Sister chromatids: two copies of DNA

• Cancer is uncontrolled cell division
