Question
Which of the following processes happen in the anaphase of mitosis?The centrioles at the two poles move apartHomologous chromosomes move toward the opposite polesMost of the DNA is replicatedThe centrioles at the two poles move apart + Homologous chromosomes move toward the opposite polesThe centrioles at the two poles move apart + Homologous chromosomes move toward the opposite poles + Most of the DNA is replicated
Solution
The processes that happen in the anaphase of mitosis are:
-
The centrioles at the two poles move apart: This is true. During anaphase, the paired centrioles separate and move to opposite ends (poles) of the cell.
-
Homologous chromosomes move toward the opposite poles: This is not entirely accurate. It's the sister chromatids (identical copies formed during the DNA replication phase) that separate and move towards opposite poles, not the homologous chromosomes. Homologous chromosomes separate during meiosis, not mitosis.
-
Most of the DNA is replicated: This is not true. DNA replication occurs during the S phase of the cell cycle, before mitosis begins.
So, the correct answer is "The centrioles at the two poles move apart".
