Abstract: | The isolation and characterization of ribosomal fractions from thoraces of Lucilia cuprina have been described and their capacity for in vitro protein synthesis studied at different stages of development. There are large differences in the yield of ribosomes during development, and these probably reflect differences in the number of ribosomes in vivo. The amino acid incorporation activity varied at different stages of development and this variation correlated with the percentage of polysomes present. Maximal activity was found just after adult emergence. Results obtained by the use of supernatant fractions from different stages of development suggest that control of protein synthesis in this insect takes place at the level of translation. |
