Duration of cell cycle in yeast-

Answer

### Step-by-Step Solution:

1. **Understanding Yeast**: Yeast is a eukaryotic, single-celled microorganism that belongs to the kingdom Fungi. This classification helps us understand its biological processes, including the cell cycle.

2. **Duration of Yeast Cell Cycle**: The duration of one complete cell cycle in yeast is approximately 90 minutes. This includes all phases of the cell cycle, such as interphase and mitosis.

3. **Comparison with Human Cell Cycle**: In contrast, the human cell cycle takes about 24 hours to complete one division. This significant difference highlights how quickly yeast can reproduce compared to human cells.

4. **Calculating Mitosis Frequency**: Given that yeast can complete its cell cycle in 90 minutes, we can calculate how many times yeast can undergo mitosis in the time it takes for a human cell to complete one cycle (24 hours).

- Convert 24 hours into minutes:
\[ 24 \text{ hours} = 24 \times 60 = 1440 \text{ minutes} \]
- Now, divide the total time for human cell division by the duration of the yeast cell cycle:
\[ \frac{1440 \text{ minutes}}{90 \text{ minutes}} \approx 16 \]
This means that yeast can perform mitosis approximately 16 times in the time it takes for one human cell to divide.

5. **Conclusion**: Therefore, the duration of the cell cycle in yeast is 90 minutes.
