Which agent or treatment would allow a cell to proceed from G₁ to metaphase and then arrest cell division at metaphase? A) a treatment that introduces breaks in the DNA B) a treatment that interferes with the replication of DNA C) a chemical that prevents contraction of the contractile ring D) a chemical that disassembles the spindle once it has formed

A chemical that disassembles the spindle once it has formed would prevent the cell from progressing past metaphase, as the spindle is crucial for chromosome alignment and separation during mitosis. Without a functional spindle, the cell cannot proceed to anaphase, leading to arrest at metaphase.
