Fundamentals of Biology: Lecture Outlines: Chapter 9 - Cell Division and Mitosis
Multicelled organisms use cell division for:
Division involves:
Chromosomes
- chromatid
Organization of Metaphase Chromosomes:
- DNA + proteins
- centromeres have disk-shaped kinetochores
Chromosome number
Cell cycle
INTERPHASE
G1
S
G2
MITOSIS
INTERPHASE
Stages of Mitosis (animal cell)
PROPHASE
TRANSITION - "Prometaphase"
-nuclear membrane breaks down
- microtubules attach
METAPHASE
ANAPHASE
- sister chromatids separate
- move
TELOPHASE
- "daughter" chromosomes reach poles
Cytokinesis - division of cytoplasm
