Final answer:
The statement is false because the correct order of mitosis phases includes prophase, prometaphase, metaphase, anaphase, and telophase. Prometaphase is an important phase following prophase and preceding metaphase that involves the attachment of microtubules to kinetochores on the chromosomes.
Step-by-step explanation:
The sequence of mitosis phases being prophase, metaphase, anaphase, and telophase is true or false is: B. False. The correct sequence includes prometaphase, which is often omitted in simplified descriptions of mitosis. The complete and accurate sequence of mitosis phases is prophase, prometaphase, metaphase, anaphase, and telophase.
During prophase, chromosomes begin to condense and the mitotic spindle starts to form. Prometaphase is characterized by the breakdown of the nuclear envelope and the attachment of spindle microtubules to kinetochores. In metaphase, chromosomes align at the metaphase plate. During anaphase, sister chromatids separate and move to opposite poles of the cell. Finally, telophase involves the reformation of the nuclear envelope and the beginning of cytokinesis, where the cell divides into two.
