Comments "From loss of radioactivity, the half-life of rRNA was 11.43, 14.85, 5.28 and 7.14 h during the initial, exponential, late exponential and stationary growth stages, respectively...The incorporation of radioactive precursors (3H-orotic acid or 14C-uracil) into rRNA indicated that cells in the exponential phase of growth displayed the highest rate of synthesis (100%)."
