Question

A cytology slide shows cells in various stages of mitotic activity. How would this sample be categorized?

1) Pleomorphism
2) Malignant
3) Anisokaryosis
4) Benign

Answer 1

Mitosis consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase, which are followed by cytokinesis, resulting in two identical daughter cells.

Step-by-step explanation:

Correct Order of Events in Mitosis

The process of mitosis is divided into several stages that a cell undergoes to divide and produce two identical daughter cells. The correct order of events in mitosis is as follows:

1. Prophase: Chromosomes condense and become visible, the mitotic spindle starts to form, and the nucleolus disappears.
2. Prometaphase: The nuclear envelope breaks down, and spindle fibers attach to chromosomes.
3. Metaphase: Chromosomes align at the metaphase plate (middle of the cell).
4. Anaphase: Sister chromatids separate and move toward opposite poles of the cell.
5. Telophase: Chromatids arrive at the poles, the nuclear envelope re-forms, and chromosomes begin to decondense.

Cytokinesis, which is often mentioned alongside mitosis, is the process where the cytoplasm divides, creating two daughter cells. Hence, the correct sequence for the options provided would be Prophase, Prometaphase, Metaphase, Anaphase, and Telophase.
