Question

In a cell cycle, during which phase are chromosomes arranged on the equatorial plate?

• A. Telophase
• B. Prophase
• C. Metaphase
• D. Anaphase

Answer 1

The correct option is C

Metaphase

During metaphase, the chromosomes get arranged in the form of a plate called the equatorial plate or metaphase plate at the equator of the spindle. This plate is at right angles to the axis of the spindle and is formed of the kinetochores, the arms of chromatids trailing away. The centromeres are drawn to the equator by the equal pull of two chromosomal fibres which connect the sister kinetochores to the opposite poles. The process of drawing the chromosomes onto the equator of the spindle is known as congression.
