Abstract
During Lineus ruber oogenesis, there is a very high uridine uptake by the oocyte before the yolk formation. At the end of this stage, the nucleolus shows a special structure that seems to be related to a decrease of the ribosomal RNA synthesis. During the yolk formation, the nucleolus scatters in the nucleus, allowing ribonucleoprotein granules to go towards the cytoplasm.
摘要
在红带沙蚕卵子发生过程中，卵母细胞在卵黄形成之前对尿苷的摄取量非常高。在这个阶段结束时，核仁呈现出一种特殊结构，似乎与核糖体RNA合成的减少有关。在卵黄形成过程中，核仁分散在细胞核中，使核糖核蛋白颗粒进入细胞质。
