During the first few days of germination, the RNA content of the cotyledons remained approximately constant, but the quantity of membrane-bound ribosomes increased. Experiments with orthophosphate-(32)P indicated that these ribosomes were synthesised de novo, and did not originate by the attachment to membranes of pre-existing free ribosomes. This conclusion was discussed in relation to the suggestion that free and membrane-bound ribosomes synthesise different groups of proteins.
在发芽的最初几天，子叶的 RNA 含量保持不变，但膜结合核糖体的数量增加。用正磷酸盐-（32）P 的实验表明，这些核糖体是从头合成的，不是由预先存在的游离核糖体附着到膜上产生的。这一结论与游离核糖体和膜结合核糖体合成不同蛋白质组的观点有关。
