A scientist looks into a microscope and sees that replicated chromosome pairs are lined up in the center of a cell. The scientist then sees the mitotic spindle from each side of the cell attach to a chromosome. Which mitotic phase is the scientist likely witnessing? (1 point)

Question

• prophase
• anaphase
• telophase
• metaphase

Answer 1

The scientist is likely witnessing metaphase. During metaphase, replicated chromosome pairs are aligned in the center of the cell, and the mitotic spindle fibers attach to the chromosomes at their centromeres.
