Document Summary
The cell cycle clock is the central governor of growth and proliferation the cell cycle is a network of proteins that respond to diff pathways such as growth factor receptors some terminology. Cell division = process that yields two daughter cells from a mother cell. Cell growth = accumulation of cellular constituents or growth of cell populations: our definition = cell growth implies both accumulation of cellular constituents and the subsequent cellular division. Cell proliferation = an increase of the number of cells as a result of cell growth and cell division. the mammalian cell cycle. When cell is stimulate by signaling pathway or mutagens, cell enters g1 phase (gap1), then s phase (dna synthesis), then g2 phase (gap2), then m phase (mitosis)- cell divides checkpoints in the cell cycle. R point -time point when the cell must make the commitment to advance through the remainder of the cell cycle (nearing end of g1)
