Synthesis of chromosomal proteins was studied by means of autoradiography in giant polytene chromosomes of Chironomus thummi. Incorporation of tryptophane-H3 into non-histone proteins of the chromosome does not increase during DNA synthesis. Grain count data reveal that chromosomes of cells which are actively replicating DNA do not differ from non-replicating cells in regard to the incorporation of tryptophane-H3 into chromosomal non-histone protein. Chromosomes of cells which are replicating DNA incorporate about 2 times more lysine-H3 than do non-DNA replicating cells. Synthesis of histones accounts for this increase in lysinc-H3 incorporation.
