De novo biosynthesis and base composition of total and ribosomal ribonucleic acids during early development in Artemia sp.

De novo synthesis of total and ribosomal ribonucleic acids has been studied during the early stages of Artemia sp. development. By in vivo incorporation studies of [14C]HCO3- an increase has been found in both total and ribosomal RNA synthesis post hatching, with a similar distribution of radioactivity and base composition.
