Abstract

We studied quantitatively the uridine 5-3H nuclear incorporation in adult ovaries of Tenebrio molitor during the oöcyte maturation. In follicular cells, the rate of RNA synthesis is constant. In the oöcytes, the precursor incorporation is maximum towards the end of previtellogenesis, and low during the yolk deposition. In nurse cells, the RNA synthesis increases during the oöcyte growth and reaches a maximum value 6.5 days after the imaginal molt.

摘要

我们定量研究了黄粉虫成虫卵巢在卵母细胞成熟过程中尿苷5-³H的核掺入情况。在滤泡细胞中,RNA合成速率恒定。在卵母细胞中,前体掺入在卵黄生成前期结束时达到最大值,而在卵黄沉积期间较低。在滋养细胞中,RNA合成在卵母细胞生长过程中增加,并在成虫蜕皮后6.5天达到最大值。
