Where do the chromosomes line up during metaphase?
AMidway between the two poles
BClose beside one of the poles
CAround the nuclear envelope
DAlong the inner cell membrane
Answer & Solution
Correct answer: A. Midway between the two poles
1. Spindle fibers from both poles pull on each chromosome at once.
2. When those pulls balance, the chromosome settles halfway between the poles.
3. That plane is called the metaphase plate or equatorial plane.
4. At this point the chromosomes are at their most condensed.
