In which phase of mitosis do chromosomes line up in the center of a cell?Group of answer choicesProphaseMetaphaseAnaphaseTelophase

Breakdown of the Problem

1. Identify the phases of mitosis.
2. Determine which phase involves the alignment of chromosomes at the cell's center.

Relevant Concepts

• Mitosis is divided into several phases: Prophase, Metaphase, Anaphase, and Telophase.
• The key characteristic of each phase includes:
  • Prophase: Chromosomes condense and become visible; the nuclear envelope begins to break down.
  • Metaphase: Chromosomes align along the metaphase plate (center of the cell).
  • Anaphase: Sister chromatids are pulled apart and move towards opposite poles.
  • Telophase: Chromosomes de-condense, and the nuclear envelope re-forms.

Analysis and Detail

• During Metaphase, the chromosomes are all lined up in the middle of the cell, preparing for separation. This alignment is essential for ensuring that each daughter cell receives an identical set of chromosomes.

Verify and Summarize

• Metaphase is characterized by the formation of a metaphase plate where chromosomes align. Thus, it is confirmed that this is the necessary phase in question.

Final Answer

The correct answer is Metaphase.
