Question

In which phase of mitosis do chromosomes align at the center of the cell?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Mitosis phases
 **Related Topics**: Cell cycle, chromosome segregation, spindle apparatus
 **Prerequisites**: Basic understanding of cell division and chromosome structure.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the phase of mitosis where chromosomes align at the cell's center (metaphase plate).
  The options are the four main phases of mitosis: prophase, metaphase, anaphase, and telophase.
**Method & Steps**:
 1. Identify the phase described.
  Reasoning:  The alignment of chromosomes at the cell's equator is a defining characteristic of a specific mitotic phase.
  Formula/Rule: None directly applicable; this is a descriptive question.
 2. Recall the events of each mitotic phase.
  Working: 
            * Prophase: Chromosomes condense, nuclear envelope breaks down.
            * Metaphase: Chromosomes align at the metaphase plate (cell's equator).
            * Anaphase: Sister chromatids separate and move to opposite poles.
            * Telophase: Chromosomes decondense, nuclear envelopes reform.
  Key Point:  The metaphase plate is crucial for ensuring equal distribution of chromosomes to daughter cells.
 3. Determine the correct phase.
  Result: Metaphase is the phase where chromosomes align at the center of the cell.
  Verification: The description perfectly matches the events of metaphase.
 ## OPTION ANALYSIS
A :x: Prophase is the stage where chromosomes condense and the nuclear envelope breaks down, not where they align at the center.
B ✓: Metaphase correctly describes the alignment of chromosomes at the cell's equator.
C :x: Anaphase is when sister chromatids separate and move to opposite poles.
D :x: Telophase is the final phase where the nuclear envelope reforms and chromosomes decondense.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing metaphase with anaphase:  Remember that alignment happens *before* separation.
  2.Overlooking the defining characteristic of each phase: Carefully study the key events of each mitotic phase.
 **Quick Tips**:
  1.Use mnemonics (e.g., PMAT) to remember the order of mitotic phases.
  2.Visualize the process using diagrams or animations.
