the rates of synthesis and half-lives of trna , 18s and 28s rrna of 14-day and 17-day embryonic chick muscle were determined by following the accumulation of radioactive amp in rna after administration of [ 3h ] 8-adenosine to chick embryos and correcting for the average specific activity of the precursor atp pool transfer rna of 14-day embryonic chick muscle is synthesized at a rate of 2.4 x 10 ( 5 ) molecules per min per 2n dna content and decays with a half-life of 50h .
