Options

A. `1xx10^(-5)`
B. 1xx10^(12)`
C. `1xx10^(-5)`
D. `1xx10^(-12)`

Answer

To solve the question regarding the frequency of mutations in nature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mutation Frequency**:
- Mutation frequency refers to the rate at which mutations occur in a given population or organism. It is usually expressed as a ratio or a number per generation or per cell division.

2. **Analyzing the Options**:
- The options provided are:
- 1 x 10^-5
- 1 x 10^12
- 1 x 10^5
- 1 x 10^-12

3. **Identifying Typical Mutation Rates**:
- In nature, mutation rates can vary widely among different organisms. For example, viruses typically have higher mutation rates compared to more stable organisms like humans.

4. **Considering Virus Mutation Rates**:
- According to the information provided, the mutation frequency in viruses can range from 1 x 10^-4 to 1 x 10^-6. The average mutation frequency is often cited as approximately 1 x 10^-5.

5. **Selecting the Correct Answer**:
- Based on the analysis, the most appropriate answer from the options provided is 1 x 10^-5, as it aligns with the average mutation frequency observed in nature.

### Final Answer:
The frequency of mutations in nature is approximately **1 x 10^-5**.
