The photomicrograph shows 17 cells in different stages of the mitotic cell cycle. [Photomicrograph of cells in different mitotic stages, with cell 1 highlighted] Which row is correct for this photomicrograph?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
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
✓ Correct answer
A: the 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
