Intracellular ribonuclease from the ciliate Tetrahymena pyriform.is GL was purified 10-fold. After preheating for 20 minutes at 100ยฐC of the ribonuclease preparation 80% of its activity was lost. Preheating under the same conditions, however, in the presence of RNA, did not affect the enzyme activit
1. The uptake of dissolved nutrients (peptone) per average digestive vacuole in starved Tetrahymena pyri/ormis is much increased by the concurrent uptake of indigestible inert particulate matter. When 0.5 and 1.1 ~m diameter polystyrene, and 2.02 ~zm polyvinyltoluene, ]atox particles together with p
## Abstract Warming of exponentially growing __T. pyriformis__ to 34ยฐC results in severe inhibition of nucleotide pool formation. The utilization of the pool for stable RNA synthesis is poorly affected at the high temperature. It thus appears that the synthesis and processing of ribosomal RNA precu
## Abstract The rate of cell division of __Tetrahymena__ growing in an observational high pressure vessel was measured at selected pressures of helium, hydrogen and at high hydrostatic pressure. Pressures greater than 100 atm reduced the rate of division, but the gases inhibited division to a lesse
