A thin, direct cytoplasmic connection between two cells through which large molecules can pass (unlike gap junctions). Common in plants (plasmodesmata) but rare in animals except between nurse cells and developing gametes. Why cytokinesis is incomplete in spermatogenesis?

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. Remember that cytokinesis is incomplete during these steps, and cytoplasmic bridges connect the cells and allow for their synchronous development. Leydig Cells
