Question
The following statements are made regarding colchicine treatment in plants for inducing polyploidy. A. In colchicine-treated cells, sister chromatids cannot separate during anaphase, leading to chromosome doubling when the nucleus reforms.B. Colchicine stimulates endoreduplication in the treated cells, bypassing cytokinesis to yield polyploid cells in a process called “C-mitosis”.C. In sterile interspecific hybrids, colchicine treatment may restore fertility by converting them into amphipolyploids.D. Colchicine treatment during meiosis has no effect, as it only acts on mitotic cells.E. Colchicine binds to tubulin and prevents spindle fibre formation during mitosis. Which one of the following options represents a combination of all correct statements?
Explanation
In the following statements are made regarding colchicine, A, C and E only represents established outcome. functional assays confirms option A (A, C and E only) as correct, while alternatives misstate substrate or regulatory direction, contradicting textbook data.
