front 1 cell division | back 1 process by which cells make more cells |
front 2 binary fission | back 2 one prokaryotic cell divides to produce two daughter cells |
front 3 steps of binary fission | back 3
|
front 4 asexual reproduction | back 4 production of organisms where offspring inherits DNA from a single parent |
front 5 mitosis | back 5 division of nucleus |
front 6 cytokinsis | back 6 division of cytoplasm into 2 daughter cells |
front 7 chromosomes | back 7 cellular structure in eukaryotes and prokaryotes that consist of single DNA molec. |
front 8 cell cycle | back 8 period from when production of a new cell to the time it divides |
front 9 m phase | back 9 parent cell divides into 2 daughter cells |
front 10 interphase | back 10 copying DNA and cell growth, broken into 3 phases |
front 11 g1 phase | back 11 cell prepares for DNA replication |
front 12 s phase | back 12 DNA molec. copied |
front 13 g2 phase | back 13 cell prepares for M phase (size and protein content of the cell increases) |
front 14 sister chromatids | back 14 DNA in chromosome duplicated into 2 identical copies |
front 15 centromere | back 15 constrictly holds together sister chromatids |
front 16 g0 phase | back 16 cells that are not actively dividing |
front 17 chromatin | back 17 highly organized complex of DNA, RNA, and proteins in chromosomes |
front 18 prophase | back 18 1st stage of mitosis |
front 19 mitotic spindle | back 19 groups of fibers made up of microtubules pull chromosomes to opposite ends of dividing cell |
front 20 cntrosome | back 20 in animal cells, the mitotic spindle radiates outward |
front 21 prometaphase | back 21 nuclear envelope breaks down and mitotic spindle attaches to the chromosomes |
front 22 kinetochores | back 22 two protein complexes associated with the centromere of each chromosome |
front 23 metaphase | back 23 when chromosomes are aligned in the middle of the dividing cell |
front 24 anaphase | back 24 next stage of mitosis, sister chromatids separate |
front 25 telophase | back 25 cell prepares for its division into 2 new cells |
front 26 cancer | back 26 mechanisms in cell division fails = death of cell or uncontrolled cell division |
front 27 cyclin-dependent kinases (CDKs) | back 27 activity depends on binding cyclins, allows cell cycle to progress |
front 28 checkpoint | back 28 the activity required for the next step and pauses the cell cycle until preparations are complete or damage is repaired |
front 29 DNA replication | back 29 duplicating a DNA molec. |
front 30 apoptosis | back 30 cells that are programmed to die |
front 31 p53 protein | back 31 DNA damaged by radiation activated that phosphorylates a protein |
