Macromolecular Events Following Nutritional Shift-Up of Tetrahymena
Tetrahymena pyriformis is a unicellular eukaryotic organism that has been much used in biochemical and physiologic studies of the cell cycle and the control of cell growth and division (Hill, 1972; Elliott, 1973). Tetrahymena has a short generation time (2 1/2 h under most conditions), can be readily grown in large amounts, is readily labelled by nucleic acid and protein precursors, and both enzymes and nucleic acids from these cells are readily isolated and handled. Also, recent technical advances have made mutant isolation and genetic analysis with this organism very feasible (Gardonio et al., 1975; Orias and Bruns, 1975).
