Which stage of mitosis is represented as 'A' in the mnemonic PMAT?

• A. Anaphase
• B. All phase
• C. Antephase
• D. Aggregate

Answer: (A)

The stage of mitosis referred to as 'A' in the mnemonic PMAT stands for Anaphase. This mnemonic helps to remember the order of the phases of mitosis: Prophase, Metaphase, Anaphase, and Telophase.

During Anaphase, the centromeres that hold the sister chromatids together divide, and the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers. This separation is crucial for ensuring that each daughter cell receives an identical set of chromosomes, maintaining genetic consistency.

Anaphase plays a vital role in the overall process of cell division, as it directly influences the distribution of genetic material. Understanding this stage within the context of the entire mitotic process is essential for grasping how cells reproduce and maintain their genetic integrity.
