Study Notes
Key Characteristics of Chromosomes in Metaphase
- Chromosomes are highly condensed and visible under a microscope, appearing as distinct entities.
- Each chromosome consists of two sister chromatids, joined at the centromere, ensuring accurate segregation during cell division.
Number of Chromosomes in Metaphase
- The number of chromosomes remains constant during metaphase and is equal to the diploid number in somatic cells.
- For example, humans have 46 chromosomes (23 pairs) during metaphase of mitosis.
Shape of Chromosomes in Metaphase
- Chromosomes typically exhibit an X-shape due to the pairing of sister chromatids.
- This shape ensures that each daughter cell receives an identical set of chromosomes.
Role of Chromosomes During Metaphase
- Chromosomes align at the cell's equatorial plane, known as the metaphase plate, facilitating proper distribution.
- Spindle fibers connect to the centromeres, ensuring precise movement toward opposing poles during anaphase.
Significance of Chromosome Shape in Metaphase
- The compact X-shaped structure minimizes entanglement, enhancing the efficiency of chromosome separation.
- Proper alignment and shape are crucial for preventing genetic anomalies in daughter cells, safeguarding genetic stability.
