Question

which process occurs during anaphase of mitosis?
chromosomes are replicated.
sister chromatids move to opposite ends of the cell.
replicated chromosomes line up in the middle of the cell.
the nuclear membrane disassembles.
two nuclear membranes form around two groups of chromosomes.

Explanation:

• Chromosome replication occurs in interphase, not anaphase.
• Replicated chromosomes lining up in the middle of the cell is metaphase.
• Nuclear membrane disassembling is prophase.
• Two nuclear membranes forming around two groups of chromosomes is telophase.
• In anaphase of mitosis, sister chromatids separate and move to opposite ends of the cell.

Answer:

Sister chromatids move to opposite ends of the cell.
