The site of histone synthesis was studied in polytene cells of the salivary glands of the Rhynchosciara americana (Diptera). It was found that, as is the case in non-polytene systems, these proteins are synthesized in the cytoplasm in a class of light polysomes which contain 3-4 ribosomes. This class of polyribosomes is most active at about 5 days before pupation when the nuclei are most active in DNA synthesis and the chromosomes of the gland show many open 'DNA puffs'.
对美洲大蠊(双翅目)唾液腺的多线细胞中组蛋白的合成位点进行了研究。结果发现,与非多线系统的情况一样,这些蛋白质在细胞质中一类含有3 - 4个核糖体的轻多核糖体中合成。这类多核糖体在化蛹前约5天最为活跃,此时细胞核在DNA合成中最为活跃,腺体的染色体呈现出许多开放的“DNA泡”。
