Abstract

Peridinium balticum is one of two dinoflagellates known to have dissimilar nuclei together in the same cell. One nucleus (dinokaryotic) has permanently condensed chromosomes, while the other (eukaryotic) does not have morphologically distinct chromosomes. Acid extracts of chromatin prepared from a mixture of dinokaryotic and eukaryotic nuclei and purified eukaryotic nuclei give four bands that co-migrate with four of the five histones from calf thymus when analyzed in urea-containing polyacrylamide gels.

摘要

波罗的海多甲藻是已知的两种在同一细胞中具有不同细胞核的甲藻之一。一个细胞核（双鞭毛核）有永久浓缩的染色体，而另一个（真核细胞核）没有形态上明显不同的染色体。当在含尿素的聚丙烯酰胺凝胶中分析时，从双鞭毛核和真核细胞核的混合物以及纯化的真核细胞核制备的染色质酸提取物产生四条带，它们与来自小牛胸腺的五种组蛋白中的四种共迁移。
