摘要：

Free ribonucleotides in plasmodia of Physarum polycephalum at different stages of the synchronous mitotic cycle were determined by anion exchange chromatography. The nucleotide pattern of this myxomycete resembled that obtained from rat liver. The contents of total adenine nucleotides based on protein content were almost identical in both tissues, whereas higher contents of guanine‐, uracil‐, and cytosine‐nucleotides were found in the myxomycete. During the mitotic cycle, the levels of nucleoside triphosphates increased just prior to mitosis and decreased in the following reconstruction period. It is suggested that the accumulation of triphosphates results from a diminished demand for RNA precursors due to decreasing RNA synthesis during late interphase. Copyright © 1969, Wiley Blackwell.
