Question

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)
• 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.
