Final answer:
In mitosis, the correct sequence of phases for the lettered cells is interphase, prophase, prometaphase, and metaphase. Interphase prepares the cell for division, prophase is when chromosomes condense, prometaphase involves the breakdown of the nuclear envelope, and metaphase is when chromosomes align for separation.
Step-by-step explanation:
Phases of Mitosis
The correct phase for each lettered cell through the stages of mitosis is as follows:
- a) Interphase - This phase is not part of mitosis proper; it's the period where the cell grows, and DNA is replicated, preparing the cell for division.
- b) Prophase - During prophase, the chromosomes condense and become visible under a light microscope.
- c) Prometaphase - In this stage, the nuclear envelope breaks down and the chromosomes start to attach to the spindle apparatus.
- d) Metaphase - The chromosomes align at the metaphase plate, at the cell's equatorial plane, in preparation for separation.
The correct order of mitosis events is prophase, prometaphase, metaphase, anaphase, and telophase, followed by cytokinesis.
An event that does not occur during some stages of interphase is the increase in cell size as all stages of interphase involve growth, but only the S-phase of interphase involves DNA duplication.
