Question Detail
Question
Which process occurs during prophase of the mitotic cell cycle in an animal cell? A. Division of centromeres B. Formation of chromosomes C. Replication of DNA D. Separation of centrioles
Correct Answer
Option D is the correct answer.
Detailed Explanation
In animal cells during prophase, the centrioles (which were duplicated in interphase) begin to move to opposite poles of the cell. This helps organize the spindle fibers. DNA replication occurs in S phase, chromosomes form/condense, and centromeres divide in anaphase.
Hint
These barrel-shaped structures move to opposite ends.
