Place the following events of mitosis in the correct order – Mitosis, the process of cell division, is a fundamental biological event that ensures the accurate transmission of genetic material to daughter cells. Understanding the correct sequence of events during mitosis is critical for maintaining genomic integrity and cellular homeostasis. This article provides a comprehensive overview of the stages of mitosis, emphasizing the importance of their proper progression.
Introduction
Mitosis is a fundamental process in cell division, ensuring the equal distribution of genetic material to daughter cells. It plays a crucial role in growth, development, and tissue repair. This article provides an overview of the stages of mitosis and their significance.
Stages of Mitosis
Prophase, Place the following events of mitosis in the correct order
Prophase marks the beginning of mitosis, characterized by chromosome condensation and the breakdown of the nuclear envelope. Chromosomes become visible and spindle fibers form to prepare for chromosome alignment.
Metaphase
During metaphase, chromosomes align at the metaphase plate, an imaginary line equidistant from the cell’s poles. Spindle fibers attach to the chromosomes, ensuring their proper separation.
Anaphase
Anaphase is characterized by the separation of sister chromatids, which are pulled apart by the spindle fibers. The chromatids move to opposite poles of the cell, resulting in two sets of chromosomes.
Telophase
Telophase marks the end of mitosis, with the formation of two new nuclear envelopes around the separated chromosomes. The chromosomes decondense and spindle fibers disappear, resulting in two daughter cells with identical genetic material.
Importance of Correct Sequence: Place The Following Events Of Mitosis In The Correct Order
The correct sequence of mitosis is crucial for accurate chromosome segregation and cell division. Errors in the sequence can lead to genetic abnormalities, developmental defects, and even cancer. Mechanisms such as checkpoints and regulatory proteins ensure the proper progression through the stages of mitosis.

Common Queries
What is the significance of mitosis in cell division?
Mitosis is essential for growth, development, and tissue repair. It ensures that each daughter cell receives an identical set of chromosomes, maintaining the genetic integrity of the organism.
What are the key events that occur during prophase?
During prophase, chromosomes condense, the nuclear envelope breaks down, and the spindle apparatus forms.
How are chromosomes aligned during metaphase?
In metaphase, chromosomes align at the metaphase plate, ensuring their equal distribution to daughter cells.
What is the role of anaphase in mitosis?
Anaphase involves the separation of sister chromatids and their movement to opposite poles of the cell.
What happens during telophase?
Telophase marks the end of mitosis, with the formation of new nuclear envelopes and the decondensation of chromosomes.
