Duplication of chromosomes without the division of nucleus is called

Options

A. Cytokinesis
B. Plasmotomy
C. Endomitosis
D. Dinomitosis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the duplication of chromosomes without the division of the nucleus.

2. **Analyzing the Options**: The options provided are:
- a) Cytokinesis
- b) Plasteromy
- c) Endomyotosis
- d) Dynamitosis

3. **Defining Cytokinesis**: Cytokinesis refers to the division of the cytoplasm during cell division. Since the question specifically mentions the duplication of chromosomes without nuclear division, cytokinesis is not the correct answer.

4. **Considering Plasteromy**: Plasteromy is not a commonly recognized term in cell biology related to chromosome duplication, so it can be ruled out.

5. **Examining Endomyotosis**: Endomyotosis is a process that involves the duplication of chromosomes without the division of the nucleus (karyokinesis). This means that the chromosomes replicate, but the nucleus does not divide, leading to cells with multiple sets of chromosomes.

6. **Reviewing Dynamitosis**: Dynamitosis is a type of cell division that involves the division of the nucleus but is not relevant to the question since it does not fit the criteria of duplication without division.

7. **Conclusion**: The correct answer is **Endomyotosis**, as it specifically describes the duplication of chromosomes without the division of the nucleus.

**Final Answer**: Endomyotosis
