A cell has 46 chromosomes at each pole in mitotic telophase. In tis division the number of chromatids at the metaphase was :-

Options

A. 23
B. 46
C. 69
D. 92

Answer

To solve the question about the number of chromatids present at metaphase when a cell has 46 chromosomes at each pole in mitotic telophase, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Chromosome Count in Telophase**:
- The question states that there are 46 chromosomes at each pole during telophase. Since telophase is the final stage of mitosis where the cell is about to divide, it indicates that the cell has completed one round of mitosis.

2. **Determine the Total Chromosome Count**:
- Since there are 46 chromosomes at each pole, the total number of chromosomes in the cell before division (during metaphase) would be 46 (from one pole) + 46 (from the other pole) = 92 chromosomes.

3. **Identify the Number of Chromatids**:
- Each chromosome is made up of two sister chromatids during metaphase. Therefore, if there are 92 chromosomes, the number of chromatids would be:
\[ \text{Number of chromatids} = \text{Number of chromosomes} \times 2 \]
\[ \text{Number of chromatids} = 92 \times 2 = 184 \]

4. **Correct the Understanding**:
- However, we need to clarify that during metaphase, the chromatids are still attached to each other. Therefore, the number of chromatids present at metaphase is equal to the number of chromosomes multiplied by 2:
\[ \text{Number of chromatids at metaphase} = 92 \]

5. **Final Answer**:
- Thus, the number of chromatids at metaphase is 92.

### Conclusion:
The number of chromatids at metaphase is **92**.
