Cytokinesis multinucleated
WebSyncytium is a term used to describe those multinucleated cells that arise through cell fusion. These "cells" are a kind of "cytoplasmic mass" that contains several nuclei enclosed in the same cell membrane. Syncytia can be seen in almost all kingdoms of life: animals, plants, fungi, and archaea. For example, during the embryonic development of ... WebHow could such multinucleated cells be explained? A) The cells underwent repeated cytokinesis but no mitosis. B) The cells had multiple S phases before it entered mitosis. C) The cells did not enter mitosis. D) The cells underwent repeated mitosis, but cytokinesis did not occur. E) The cells underwent repeated mitosis with simultaneous cytokinesis.

WebAug 14, 2012 · To determine whether NAC1 was essential for effective cytokinesis, we reintroduced NAC1 expression in Nac1-null cells to determine whether ectopic NAC1 would prevent the multinucleated phenotype. For this purpose, we used a Nac1 homozygous knockout (Nac1 −/− ) mouse in which both copies of the BTB domain of the mouse … Syncytia can also form when cells are infected with certain types of viruses, notably HSV-1, HIV, MeV, SARS-CoV-2, and pneumoviruses, e.g. respiratory syncytial virus (RSV). These syncytial formations create distinctive cytopathic effects when seen in permissive cells. Because many cells fuse together, syncytia are also known as multinucleated cells, giant cells, or polykaryocytes…

Multinucleate cells (also known as multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide simultaneously or asynchronously where individual nuclei divide independently in time and space. Certain organisms may have a multinuclear stage of their life cycle. For example, slime molds h… dark blue techWebAug 19, 2024 · Karyogamy is the fusion of nuclei and leads to the production of a diploid zygote. The zygote will grow, replicating the nuclei with no cytokinesis, to form the multinucleate plasmodium. A mature plasmodium (multinucleated free-flowing mass of protoplasm) can produce sclerotium (small cells) in a dry habitat. Summary bisbee seat cushion replacementWebMar 1, 2024 · This leads to conditions such as aneuploidy, where a cell has several extra or missing chromosomes; polyploidy, where cytokinesis does not occur and a cell has more than a diploid set of chromosomes; or multinucleated cells, where more than one nucleus is present in a cell.
