Question
Match the descriptions below with the following stages of mitosis, in the correct order:Prophase; Anaphase; and Cytokinesis.A. Centrioles are found at the poles; Microtubules attach to centromeres; Chromosomes condenseB. Chromosomes align along the metaphase plate; Chromosomes split at the centromere; Microtubules attach to centromereC. Chromosomes shorten and thicken; Chromosomes split at the centromere; Cytoplasm dividesD. Centrioles are found at the poles; Chromosomes split at the centromere; Chromosomes arrive at opposite polesE. Chromosomes shorten and thicken; Chromosomes arrive at opposite poles; Cytoplasm divides
Solution
The correct order of the stages of mitosis with their descriptions is as follows:
-
Prophase: This is described in option E. "Chromosomes shorten and thicken; Chromosomes arrive at opposite poles; Cytoplasm divides". However, this description is not entirely accurate. A more accurate description of prophase would be: "Chromosomes condense and become visible; nuclear envelope breaks down; nucleolus disappears."
-
Anaphase: This is described in option D. "Centrioles are found at the poles; Chromosomes split at the centromere; Chromosomes arrive at opposite poles". This stage involves the separation of sister chromatids, which are then pulled towards opposite poles of the cell.
-
Cytokinesis: This is described in option C. "Chromosomes shorten and thicken; Chromosomes split at the centromere; Cytoplasm divides". During this stage, the cytoplasm of the cell divides, creating two separate cells.
Please note that the descriptions provided in the question are not entirely accurate and seem to mix elements from different stages of mitosis. For example, the alignment of chromosomes along the metaphase plate actually occurs during metaphase, not anaphase or prophase. Similarly, the splitting of chromosomes at the centromere occurs during anaphase, not prophase or cytokinesis.
