WebMar 2, 2024 · Abstract. Chromatids of mitotic chromosomes were suggested to coil into a helix in early cytological studies and this assumption was recently supported by chromosome conformation capture (3C) sequencing. Still, direct differential visualization of a condensed chromatin fibre confirming the helical model was lacking. WebQuestion: 1. Which of the following events occurs in mitotic metaphase?
