Which of the following events of mitosis is CORRECTLY matched with its phase?
A)Metaphase - chromosomes shorten and thicken to become visible
B)Telophase - chromosomes line up down the middle of the cell
C)Prophase - chromosomes attach to spindle fibers
D)Anaphase - new nuclear envelops form around chromosomes

Question

Quizplus · Accepted Answer

During prophase, the chromatin condenses and becomes visible as distinct chromosomes. The spindle fibers also begin to form and attach to the chromosomes.

The other options are incorrect:
A) Metaphase - chromosomes line up down the middle of the cell, they don't shorten or thicken at this point
B) Telophase - chromosomes have already lined up during metaphase, during telophase they begin to uncoil and the nuclear envelope reforms around them, but they are not lining up again
D) Anaphase - the chromatids are pulled apart by the spindle fibers and move towards opposite poles of the cell, the nuclear envelope does not form at this stage.
