Yeast cell can progress through the cell cycle in about

Options

A. 90 sec
B. 90 min
C. 90 hrs
D. 90 yrs

Answer

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle is a series of events that occur in a cell, including the duplication of DNA and organelles, followed by cell division.

2. **Phases of the Cell Cycle**: The cell cycle consists of several phases:
- **G1 Phase**: The cell grows and synthesizes proteins.
- **S Phase**: DNA replication occurs.
- **G2 Phase**: The cell continues to grow and prepares for division.
- **M Phase**: The cell divides (mitosis).

3. **Duration of the Cell Cycle in Yeast**: The question specifically asks about yeast cells. Research indicates that yeast cells can complete their entire cell cycle in approximately **90 minutes**.

4. **Options Analysis**: The options provided are:
- 90 seconds
- 90 minutes
- 90 hours
- 90 years

From the analysis, we can see that:
- 90 seconds is too short.
- 90 hours and 90 years are excessively long.
- Therefore, the correct answer is **90 minutes**.

5. **Conclusion**: Yeast cells can progress through the cell cycle in about **90 minutes**.
