|
Chromosome |
packages of Dna that has genetic material bundled into it. |
|
|
Chromatin |
complex of chromosomes and proteins. |
|
|
interphase |
in btwn period of growth. seperated into 3 stages. |
|
|
G 1 phase |
when cells do most of their growing, make new proteins and organelles. |
|
|
s Phase |
s for synthesis. Dna is synthesized when chromosomes replicated. at end, contains twice as much dna as it did at the beginning. |
|
|
g2 phase |
shortest phase usually,things required for CD are produced, after phase, the cell is ready for CD. |
|
|
M phase: |
cell divisionphase, makes 2 daughter cells, |
|
|
mitosis |
division of the cell nucleus |
|
|
cytokinesis |
division of cytoplasm |
|
|
prophase |
1st stage of mitosislongest phase may take up to half time top complete mitosis, nucleus gene material condenses, |
|
|
centromere |
area where duplicated strands of DNA can be seen to be attached along their length. |
|
|
chromatid |
each DNA strand in duplicated chromosome. |
|
|
centrioles |
tiny paired structures that are located at the centrosome. |
|
|
anaphase |
3rd phase of mitosis: chromosomes seperate and move along spindle fibers to opposing ends of cell. |
|
|
Telophase |
4th phase of mitosis: chromosomes begin to spread out in a tangle of chromatin. |
|
|
cytokinesis |
completes cell division, splits one cell into two. |
|
|
cyclin: |
protein that regulates cell cycle. |
