Question
In which of the following stage of the cell cycle, the attachment of spindle fibres to kinetochores of chromosomes occurs?
Solution
The attachment of spindle fibers to kinetochores of chromosomes occurs during the Prometaphase stage of the cell cycle. Here's a step-by-step breakdown:
-
Interphase: This is the stage where the cell prepares for division by replicating its DNA.
-
Prophase: The chromosomes condense and become visible. The nuclear envelope breaks down.
-
Prometaphase: This is the stage you're asking about. The chromosomes are fully condensed and the spindle fibers attach to the kinetochores of the chromosomes.
-
Metaphase: The chromosomes align at the metaphase plate (equator of the cell).
-
Anaphase: The sister chromatids separate and move towards opposite poles of the cell.
-
Telophase: The chromosomes decondense and the nuclear envelope reforms.
-
Cytokinesis: The cytoplasm divides, resulting in two daughter cells.
