Which of the following occurs more than one and less than five in a chromosome?

Options

A. Chromatid
B. Chromosome
C. Centromere
D. Telomere

Explanation

To solve the question "Which of the following occurs more than one and less than five in a chromosome?" we need to analyze each option provided:

1. **Chromatid**: A chromosome consists of two sister chromatids, especially during the metaphase stage of cell division. Therefore, the number of chromatids in a single chromosome is exactly 2, which fits the criteria of being more than one but less than five.

2. **Chromosome**: A chromosome is a single structure, so it occurs only once in this context. This does not fit the criteria of being more than one.

3. **Centromere**: Each chromosome has one centromere that holds the two sister chromatids together. Thus, it occurs only once per chromosome, which does not meet the criteria of being more than one.

4. **Telomere**: Each end of a linear chromosome has a telomere. Since a chromosome has two ends, it has two telomeres. This also fits the criteria of being more than one but less than five.

Now, let's summarize the findings:

- **Chromatid**: 2 (fits the criteria)
- **Chromosome**: 1 (does not fit)
- **Centromere**: 1 (does not fit)
- **Telomere**: 2 (fits the criteria)

Given that both chromatids and telomeres meet the criteria of occurring more than one and less than five, we can conclude that the correct answer is:

**Answer: A. Chromatid and D. Telomere**
