Chromosome behaviour in mitosis — practice question

The photomicrograph displays 17 cells in different stages of the mitotic cell cycle. Which row matches this photomicrograph?

  • Athe role of a centromere in cell 1: attaches daughter chromosomes to spindle fibres; the proportion of the cells in the photomicrograph in telophase: > 0.2
  • Bthe role of a centromere in cell 1: holds sister chromatids together; the proportion of the cells in the photomicrograph in telophase: > 0.2
  • Cthe role of a centromere in cell 1: attaches daughter chromosomes to spindle fibres; the proportion of the cells in the photomicrograph in telophase: < 0.2
  • Dthe role of a centromere in cell 1: holds sister chromatids together; the proportion of the cells in the photomicrograph in telophase: < 0.2
