division of the nucleus
division of the cytoplasm
regulatory proteins; control entry into S phase and M phase
initiates M phase
phosphorylates key proteins in the cell that are required to initiate the cell cycle
protein complexes that hold together sister chromatids
help carry out chromosome condensation
responsible for cytokinesis; consists mainly of actin filaments and myosin filaments
principal microtuble-organizing center in animal cells
serve as nucleation sites for growth of microtubules that radiate out from the centrosome
process by which microtubules alternate between growing and shrinking
assembles on condensed chromosome; attach chromosomes to spindle microtubules
promotes the destruction of specific proteins by catalyzing their ubiquitination
programmed cell death
large protein complex that is bound to the DNA at origins of replication in eukaryotic chromosomes throughout the cell cycle
block the assembly or activity of one or more cyclin-Cdk complexes
protease that carries out apoptosis
the main proteins that regulate the activation of procaspases
inactive precursors to caspases
stimulate cell division, primarily by overcoming the intracellular braking mechanisms that tend to block progression through the cell cycle
stimulate cell growth by promoting the synthesis and inhibiting the degradation proteins and other macromolecules
promote cell survival by suppression apoptosis
a secreted signal protein that normally inhibits the growth and proliferation of the mypblasts that fuse to form skeletal muscle cells
cytochrome c + adaptor + procaspase-9
plant cell specific structure that mediates the assembly of a new cell wall in late cytokinesis
