Chapter 3D Flashcards
Mitosis
Diving the nucleus.
Cytokinesis
Division of the cytoplasm
Cell Cycle
Life and times of a cell.
Highly mitonic
Main job is to just divide cells.
Amitonic
Without cell division.
Order of mitosis
Interphase, Prophase, Metaphase, Anaphase, and Telophase.
Steps of Interphase
1.) Regular cell functions
2.) DNA is in chromatin form
3.) DNA replicated
Steps of prophase
1.) DNA condenses into chromosomes
2.) The nuclear envelope dissolves
3.) Spindle fibers begin tot form at the poles
Steps of metaphase
1.) Chromosomes line up single file at the cellular equator
2.) Spindle fibers attach at the centromeres
3.) Centromeres replicate or get broken in half
Anaphase
1.) Sister chromatids separate
2.) Chromosomes move towards opposite poles
3a.) Cytokinesis begins
3b.) Temporarily has 2 chromosomes
Telophase
1.) Chromosomes arrive at the poles
2.) Nuclear envelope returns
3.) Cytokinesis finishes
