Fertilized mouse ova were injected with messenger RNA for rabbit globin. The ova were labelled with [H]leucine and the synthesized rabbit a-globin measured by immunoprecipitation. Injection of rabbit globin mRNA from 4-0 to 15-8pg/ovum resulted in the synthesis of ~1200 dpm/ovum of a-globin during an 18 h incubation. A concentration of mRNA that was translated below the maximum level of globin ...
