Multiple Choice

Which of the following best explains a distinction between metaphase and anaphase during mitosis?

In metaphase, DNA replication occurs, while in anaphase, DNA is transcribed into RNA.

In metaphase, the nuclear envelope re-forms, while in anaphase, the nuclear envelope breaks down.

In metaphase, the cell prepares for cytokinesis, while in anaphase, the cell undergoes cytokinesis.

In metaphase, chromosomes align at the cell's equatorial plane, while in anaphase, sister chromatids are pulled apart to opposite poles.

Verified step by step guidance

Understand the stages of mitosis: Mitosis is divided into several stages, including prophase, metaphase, anaphase, and telophase. Each stage has distinct events that occur within the cell.

Identify the key event in metaphase: During metaphase, chromosomes align at the cell's equatorial plane, also known as the metaphase plate. This alignment ensures that each daughter cell will receive an identical set of chromosomes.

Identify the key event in anaphase: In anaphase, the sister chromatids, which are identical copies of a chromosome connected by a centromere, are pulled apart by the spindle fibers. They move toward opposite poles of the cell.

Compare metaphase and anaphase: The main distinction between these two stages is the position and movement of the chromosomes. In metaphase, chromosomes are aligned at the center, while in anaphase, they are separated and moved to opposite ends of the cell.

Eliminate incorrect options: Review the provided options and eliminate those that do not accurately describe the events of metaphase and anaphase. The correct distinction is that in metaphase, chromosomes align at the equatorial plane, and in anaphase, sister chromatids are pulled apart to opposite poles.
