|
Cell cycle
|
Repeated pattern of growth and division in eukaryotic cells
|
|
Interphase
|
The cell grows and duplicates its DNA; 3 parts-G1, S, and G2
|
|
G1 and G2
|
Cell grows and makes proteins
|
|
S (interphase)
|
DNA duplicates
|
|
Where does a cell spend most of its time?
|
Interphase
|
|
Chromosome
|
One long strand of DNA; a condensed bundle of chromatin that appears during cell division
|
|
Chromatin
|
The DNA and proteins in the nucleus of a non-dividing cell; "loose DNA"
|
|
Histone
|
Protein; DNA is wrapped around histones
|
|
Chromatid
|
Half of a duplicated chromosome; if there is two they are called sister chromatids and they are identical
|
|
Centromere
|
Holds sister chromatids together; "pinched" region of chromosome
|
|
Mitosis
|
Division of the nucleus and its contents; PMAT; followed by cytokinesis
|
|
Prophase
|
Chromatin condenses to become chromosomes; nucleolus and nuclear membrance disappears; centrioles go to opposite sides of cell; spindle fibers form and extend across the cell
|
|
Metaphase
|
Chromosomes line up in middle; spindle fibers attach to centromere of each chromatid
|
|
Anaphase
|
Sister chromatids seperate and become chromosomes; seperated chromatids move to opposite sides of the cell
|
|
Telophase
|
Chromosomes uncoil; nuclear membrane forms; spindle fibers break down and dissolve; cytkinesis begins
|
