Which of the following describes the location of the chromosomes during metaphase?
A
Chromosomes are condensed and visible, but still within the nuclear envelope.
B
Chromosomes are aligned at the center of the cell, known as the metaphase plate.
C
Chromosomes are decondensing and the nuclear envelope is reforming.
D
Chromosomes are being pulled apart toward opposite poles of the cell.
Verified step by step guidance

Step 1: Begin by understanding the phases of mitosis. Metaphase is one of the stages of mitosis, which is the process of cell division. It follows prophase and precedes anaphase.
Step 2: Recall the key events of metaphase. During metaphase, chromosomes are fully condensed and visible under a microscope. They are aligned at the center of the cell, forming a structure called the metaphase plate.
Step 3: Compare the descriptions provided in the problem with the characteristics of metaphase. The correct description should match the alignment of chromosomes at the metaphase plate.
Step 4: Eliminate incorrect options. For example, chromosomes being within the nuclear envelope describes prophase, decondensing chromosomes and reforming the nuclear envelope describes telophase, and chromosomes being pulled apart toward opposite poles describes anaphase.
Step 5: Confirm that the correct answer is: 'Chromosomes are aligned at the center of the cell, known as the metaphase plate,' as this accurately describes the location of chromosomes during metaphase.
