Résumé : Isolated chloroplasts from anucleate fragments of Acetabularia actively incorporate a mixture of radioactive amino acids into proteins. This incorporation is inhibited by chloramphenicol and puromycin but appears to be relatively insensitive to streptomycin, ribonuclease (EC and deoxyribonuclease (EC Actinomycin D, at a concentration of 166 μg/ml, totally inhibits the incorporation of amino acids by chloroplasts of algae enucleated 11 days previously. It is concluded that, at this time, the synthesis of chloroplastic proteins is dependent on chloroplastic deoxyribonucleic acid. © 1965.
