Question

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

Explanation:

• In anaphase of mitosis, the sister chromatids separate at the centromere and are pulled by spindle fibers to opposite ends of the cell.
• Formation of two nuclear membranes around chromosome groups occurs in telophase.
• Replicated chromosomes lining up in the middle of the cell is metaphase.
• Chromosome replication happens in the S - phase (interphase).
• Disassembly of the nuclear membrane is in prophase.

Answer:

Sister chromatids move to opposite ends of the cell.
