Which stage of mitosis has all chromosomes lined up midway between the poles?
AProphase
BAnaphase
CMetaphase
DTelophase
Answer & Solution
Correct answer: C. Metaphase
1. Each stage of mitosis has a signature chromosome arrangement.
2. One stage has them all in a single plane.
3. During metaphase, all the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell.
4. In anaphase they have already begun to move apart.
