Cytoplasm bridges

WebThe cytoplasmic bridges that form by incomplete cytokinesis are large enough (diameter range of ~0.2–10 m, see Table 1) to μ allow organelles and/or macromolecules to pass.11 This thus rep-resents a very intimate and direct type of intercellular commu-nication and complements the multitude of ways by which cells WebTrue intercellular bridges affording protoplasmic continuity between cells are reported as a normal occurrence in the clusters of spermatocytes and spermatids in the germinal epithelium of the testis. Similar bridges are found in the groups of cnidoblasts in the ectoderm of Hydra.

WebThe yeast RNA exosome consists of a highly conserved 9-subunit core complex and two catalytic subunits, Rrp44 and Rrp6. Rrp44 is bound with exosome core both in cytoplasm and nucleus, while Rrp6 is unique in nucleus. The yeast cytoplasmic exosome has a Ski7 protein that bridges the complex to Ski complex for degradation of aberrant mRNAs.

WebThe products of meiosis are the haploid spermatids, which contain dark, round nuclei and a decreasing amount of cytoplasm. These differentiate further into spermatozoa.
