using a light-driven system of protein synthesis it is shown that up to ten ribosomal proteins of the 30s and eight proteins of the 50s subunits are made in the chloroplast.newly synthesized ribosomal subunits have been analysed on cscl gradients after sedimentation at equilibrium , allowing the separation of fully assembled subunits from incomplete ribosomal particles .
