Which type of chromosome is present in the prophase of cell cycle?

Options

A. 2 chromatid
B. 1 chromatid
C. 4 chromatid
D. 8 chromatid

Answer

To answer the question "Which type of chromosome is present in the prophase of the cell cycle?", we will analyze the characteristics of chromosomes during the prophase stage.

### Step-by-Step Solution:

1. **Understanding Chromosome Structure**:
- Chromosomes are made up of DNA and proteins and exist in a condensed form during cell division. Each chromosome consists of two sister chromatids joined at a region called the centromere.

2. **Identifying the Stage**:
- Prophase is the first stage of cell division (both mitosis and meiosis). During this stage, chromosomes condense and become visible under a microscope.

3. **Chromatid Count in Prophase**:
- In prophase, each chromosome is made up of two sister chromatids. This means that if we consider the total number of chromosomes, each one will have two chromatids.

4. **Applying the Knowledge to the Question**:
- The question asks for the type of chromosome present in prophase. Since each chromosome consists of two chromatids, the answer is "2 chromatid".

5. **Conclusion**:
- Therefore, the correct answer to the question is "2 chromatid".

### Final Answer:
**2 chromatid**
