Nasmyth, Disjunction of homologous chromosomes in meiosis I depends on proteolytic cleavage of the meiotic cohesin Rec8 by separin, Cell 103 (2000) 387-398.Buonomo SBC, Clyne RK, Fuchs J, Loidl J, Uhlmann F, Nasmyth K (2000) Disjunction of homologous chromosomes in meiosis I depends on ...
When they separate during Anaphase I, the homologous chromosomes move to opposite poles, but the sister chromatids remain attached. 5. Metaphase II: In Metaphase II, the chromosomes (now consisting of two sister chromatids) align at the equator again, but this time there is no homologous ...
In meiosis, two sets of chromosomes are divided among four nuclei, each of which then has half as many chromosomes as the original cell. Four haploid cells are the result of two successive nuclear divisions. The micrographs show meiosis in the male reproductive organ of a lily; the diagrams ...
homologous chromosomes must first pair and then separate at the first meiotic division before sister chromatids separate at the second meiotic division. So, chromosome interactions between homologues are a unique feature of meiosis and are essential for proper chromosome segregation. Pairing and locking ...
The conditions re reviewed that must be met by any model of long distance attraction and transport of homologous chromosomes to the points of intimate DNA synapsis. A proposal for possible mechanisms is presented. It includes transcription and repair factors acting on coding sequences as a ...
When homologous chromosomes pair up in meiosis, this is called: a. replication. b. synapsis. c. cytokinesis. d. segregation. Homologous chromosomes : Chromosomes are homologous when they share the same evolutionary origin; they also form so-called hom...

英语翻译 原文: Process of Meiosis Unlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round of division,two intermediate daughter cells are produc...
How does the main outcome of the four stages of meiosis II separate sister chromatids and not homologous chromosomes? What is the difference between homologous chromosomes and a homologous chromosome pair? What is the difference between homologous chromosomes and homologues?
