Document Summary
Mpf maturation promoting factor, cell cycle checkpoint that regulates the passage of a cell from g2 to m phase (g2 checkpoint) Ensures dna replication during s phase did not produce mistakes. Makes sure that the cell grew enough during g2. Condensin large protein complexes that play a role in chromosome assembly & segregation during mitosis and meiosis. Cohesin protein complex that regulates the separation of sister chromatids during cell division, in mitosis or meiosis. Lamina a thin meshwork composed of intermediate filaments that lines the inner surface of the nuclear envelope. Centrosome a complex structure that contains two barrel-shaped centrioles surrounded by amorphous, electron-dense pericentriolar material (pcm) where mts are nucleated. Centrioles cylindrical structures, found in pairs, composed mainly of tubulin protein. Spindle apparatus cytoskeletal structure that forms during cell division to separate sister chromatids b/w daughter cells (mitotic/meiotic spindle) Dynein motor protein in which the cell converts atp to mechanical energy.
