ATP--dependent contraction has been observed in cortices isolated from the dividing eggs of the pond snail and treated with fragments of the skeletal muscle myosin. The motive force of cytokinesis can be tentatively attributed to the enclosed cortica

In the normal two-celled embryos of various pulmonate molluscs, the orientation of spindles characteristic of metaanaphase is being frequently established gradually, in the process of transition from pro- to metaphase accompained by the growth of spi

The zygotes of Lymnaea stagnalis L. were centrifuged and, as a result, normal and small size zygotes were obtained. The small zygotes either contained the major part of heavy yolk granules and were characterized by complete cortical polarity, or were

On the basis of the published and authors' data, a suggestion is put forward to one effect that during the early embryogenesis polysomes might bind myosin and interact with actin microfilaments, this interaction activating the contractile function of

In the normal development of pulmonate molluscs, the variety of orientations of the III and IV cleavage spindles markedly reduces in the process of transition from pro- to meta- and anaphase. Even prior to the completion of spindle growth in these cl
