Abstract
The size of the deoxyribonucleoside triphosphate pools of vitamin B-12-deficient cells of Euglena gracilis, and of vitamin B-12-deficient cells repleted with the vitamin, were measured. We found that the pools were very small, if they exist at all, in deficient cells but expand rapidly with the addition of the vitamin. The sizes of the pools decrease when DNA synthesis is completed, and are very small when the cells begin to divide.
摘要
对纤细裸藻维生素B - 12缺乏细胞以及补充该维生素后的维生素B - 12缺乏细胞中的脱氧核糖核苷三磷酸池大小进行了测量。我们发现，在缺乏维生素的细胞中，这些池即便存在也非常小，但随着维生素的添加会迅速扩大。当DNA合成完成时，池的大小会减小，而当细胞开始分裂时，池的大小则非常小。
