Researchers have determined that the chemical colchicine 1 point stops cell division by preventing the formation of spindle
fibers. Without these fibers, the sister chromatids cannot
separate properly into the daughter cells during anaphase, and
cytokinesis cannot occur. However, the cell may continue to
make copies of its chromosomes. As a result, the nucleus of
the cell contains multiple sets of chromosomes, a condition
called polyploidy. Which of the following statements can be
supported by the evidence in the text? *
The nucleus is unable to reform during telophase of mitosis.
Cells treated with colchicine may have half as much DNA as the parent
cell.
Colchicine affects the number of cells that are able to go through
interphase.
Cells treated with colchicine may have 2 or more times as much DNA
as a parent cell.
