What separates during Anaphase II?a) The cytoplasm.b) Sister Chromatids.c) Homologous chromosomes.d) Daughter nuclei.
During anaphase identical sister chromatids separate and move towards opposite poles of the mitotic spindle. In the spindle, kinetochore microtubules have their plus ends embedded in the kinetochore and their minus ends at the spindle pole. Two models have been proposed to account for the movement ...
Separation and Distribution: During mitotic anaphase or meiotic anaphase II, the cohesin protein complex cleaves leading to the dissolution of the cohesion between sister chromatids. As sister chromatids separate, they start moving towards the cell’s opposite poles, hence ensuring an equal distribution...
Replicated genomic loci often separate many hours prior to mitosis, shortly after their respective replication, such that in gap 2 (G2) cells they often localise as far apart as in mitosis[44–48]. However, the bulk DNA of sister chromatids does not resolve to the extent that it can be ...
Related to Sister chromatid:Sister chromatid exchange chro·ma·tid (krō′mə-tĭd) n. Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes. ...
During meiosis, crossing over occurs between View Solution The events shown below occur during different phases - A. Centromere splits, chromatids separate and move to opposite poles, chromatids are now called chromosome B. Chromosomes cluster at opposite poles, decondensation of chromosome, reappeara...
The separation of sister chromatids during anaphase involves the proteolysis of the cohesin Scc1p, a process that requires Esp1p. To determine whether transient sister chromatid separation also requires cohesin degradation, we synchronized temperature-sensitive esp1 cells in α factor, released them in...
Mitosis and meiosis both rely on cohesin, which embraces the sister chromatids and plays a crucial role for the faithful distribution of chromosomes to daughter cells. Prior to the cleavage by Separase at anaphase onset, cohesin is largely removed from c

ICRF-193-treated PICH−/− cells undergo sister chromatid non-disjunction in anaphase, and frequently abort cytokinesis. PICH co-localizes with Topo IIα on UFBs and at the ribosomal DNA locus, and the timely resolution of both structures depends on the ATPase activity of PICH. Purified ...
