摘要: Synthesis and transport of proteins to the cell nucleus during puff induction was studied in S. coprophila. Changes grain distribution along chromosomes (L-methionine [35S] incorporation into protein) were correlated with puffs induced by ecdysterone vitro; A pattern specific labelling at sites incipient noted within 2 h after addition hormone, i.e. grains on clusters, characteristic for this time point not seen controls (where only non-specific labeling 0-4 h). Characteristic chromosomal appeared between 3-4 ecdysterone. It concluded that ecdysterone-induced formation salivary gland chromosomes, which had been previously synthesized selectively transported from cytoplasm chromosomes.
