Question

question 17
identify the following steps in the order shown (a, b, c, d) - which is not necessarily the correct sequence in the cell cycle.
o a metaphase, interphase, cytokinesis, prophase
o b metaphase, prophase, telophase, anaphase
o c prophase, telophase, anaphase, metaphase
o d anaphase, telophase, interphase, metaphase

Explanation:

• Option a: Metaphase (chromosomes align at equator), interphase (cell growth and DNA replication), cytokinesis (cell division), prophase (chromosome condensation) - Incorrect order as interphase should come first.
• Option b: Metaphase, prophase (should come before metaphase), telophase, anaphase (should come before telophase) - Incorrect order.
• Option c: Prophase, telophase (should come after anaphase), anaphase (should come after metaphase), metaphase (should come after prophase) - Incorrect order.
• Option d: Anaphase (chromatids separate), telophase (nuclear envelope reforms), interphase (cell growth), metaphase (should come before anaphase) - Incorrect order.

Answer:

All options (a, b, c, d) have incorrect sequences as they do not follow the correct order of cell cycle phases (interphase, prophase, metaphase, anaphase, telophase, cytokinesis).
