Long, thin strands of DNA
Chromotin
-
Short, thick strands of DNA during mitosis
Chromosome
-
1/2 of a duplicated chromosome
sister chromotid
-
Place where 2 chromotids join
Centromere
-
90% of a cell cycle
interphase
-
process by which duplicated chromosomes divide
mitosis
-
Fibers that pull apart chromotids during mitosis and meiosis
spindle
-
disease of uncontrolled mitosis
cancer
-
Reproductive cell division where chromosome number is halved
meiosis
-
Cytoplasm divides in two, after mitosis, two daughter cells result
Cytokiesis
-
The process by which all cells come from other cells
mitosis
-
why cells divide
In order to grow, repair damaged cells, reproduce
-
Where does cell division occur in organisms?
in the nucleus
-
Events of cell cycle
- Interphase- When a cell grows, chomotin doubles, and preperation for mitosis
- Prophase- duplicated chromosomes shorten+thicken
- Metaphase- duplicated chromosomes line up
- Anaphase- duplicated chromosomes are pulled apart
- Telophase- new daughter cells prepare to split
