Question
Map Sapling Learning Cohesin is a protein complex that regulates the segregation of chromatids during cell division by maintaining the bond between chromatids. How is cohesin tagged differently in mitosis and meíosis to allow for proper segregation of chromatids? 4 In mitosis and meiosis II, chromatid segregation follows cohesin cleavage by the protein separase. In meiosis I, the protein shugosin prevents cohesin cleavage at the centromeres ensuring that homologous chromosomes segregate before sister chromatids separate 6 9 O In mitosis, the protein cohesin is recruited to the cell to facilitate chromatid segregation by the homologous chromosomes and sister chromatids by the protein separase The protein shugosin cleaves cohesin in mitosis and meiosis Il to allow for the segregation of ensuring that homologous chromosomes segregate before sister chromatids separate O protein shugosin. In meiosis, cohesin is recruited to the cell to control segregation of O chromatids. The protein separase prevents cleavage of cohesin at the centromeres in meiosis I The protein cohesin binds to the protein separase to encourage chromatid segregation during mitosis. To allow for the separation of both the homologous c sister chromatids in meiosis lI, cohesin binds to the protein shugosin to encourage segregation Previous Give Up & View Solution Check Answer xt- Exit HintExplanation / Answer
Ans:1)a ) In mitosis and meiosis II ,chromatid segregation follows cohesion by the protein separase.In meiosis I,the protein shugosin prevents cohesion cleavage at the centromeres,ensuring that homologous chromosomes segregate before sister chromatids separate
