Physiological role of 70S ribosomes in bacteria.

Evidence is presented indicating that free 70S ribosomes are real components of Bacillus stearothermophilus and Escherichia coli in exponential and stationary phases of growth. After pulses of radioactive leucine or uracil were given, protein synthesis was instantaneously stopped by chloramphenicol, or polypeptide growth was allowed to proceed to completion… CONTINUE READING
