Mitotic sister chromatid segregation翻译
Web26 jul. 2002 · This process, known as mitosis, involves the attachment of sister chromatids to microtubules of opposite polarity (amphitelic attachment) and their traction to opposite poles of the cell, known as bi-orientation ( Figs. 1 and 3 ). Microtubules usually attach to chromosomes at unique loci called centromeres ( Fig. 3 ). WebSimilar to the segregation events of mitosis, the pairs of sister chromatids resulting from the separation of bivalents in meiosis I are further separated in anaphase of meiosis II. In oocytes, one sister chromatid is segregated into the second polar body, while the other stays inside the egg.
