The availability of bacterial ribosomal subunits has allowed the detailed study of the mechanisms and control of protein synthesis in prokaryotes (1,2). Techniques for the isolation of active subunits of eukaryote ribosomes are now available (3,4) ; the separation of subunits is achieved by gradien

The equilibrium adsorption at 20 degreesC of molybdophosphoric acid solutions, using ethanol-water as solvent, on titania was studied. The molybdenum adsorption isotherm showed a sigmoidal shape; low values of molybdenum adsorbed were observed for final equilibrium concentrations lower than 50 mg Mo
The addition of an appropriate mixture of ethanol, water and sodium perchlorate to crude extracts of some biological material results in the selective precipitation of nucleic acids. Detergent extracts of tissue-cultured plant cells treated with this reagent yielded as much as 95-100% of the nucleic
## Abstract The thermal denaturation curves of DNA have been investigated over a wide range of temperatures __T__ and ethanol concentrations __C__ by CD and uv absorption methods. The phase diagram of conformational DNA states has been constructed in __T__,__C__ plane. The range of the A, B, and co
## Abstract The precipitation polymerization of styrene‐trihydroxymethyl propane triacrylate has been carried out using ethanol and an ethanol/water mixture as the solvent. Uniform microspheres with high monomer conversion are achieved within 4 h, a much shorter polymerization time than that report
