Read the given statements and select the correct option
Statement 1 : PCR technique is helpful in detecting bacterial and viral diseases even when symptoms of the disease are not yet visible
Statement 2 : Very low concentrations of bacteria or viruses in human body can be detected by amplification of their nucleic acids using the PCR technique

Options

A. Both statements 1 and 2 are correct
B. Statement 1 is correct but Statement 2 is incorrect
C. Statement 1 is incorrect but Statement 2 is correct
D. Both statements 1 and 2 are incorrect

Answer

To solve the question, we need to analyze the two statements provided and determine their accuracy regarding the PCR (Polymerase Chain Reaction) technique.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- The statement claims that the PCR technique is helpful in detecting bacterial and viral diseases even when symptoms of the disease are not yet visible.
- **Analysis**: PCR is indeed a powerful diagnostic tool that can amplify the genetic material of pathogens (bacteria and viruses). This means that even if the pathogen is present in low quantities and symptoms have not yet manifested, PCR can still detect its presence by amplifying its nucleic acids.

2. **Understanding Statement 2**:
- The statement asserts that very low concentrations of bacteria or viruses in the human body can be detected by amplification of their nucleic acids using the PCR technique.
- **Analysis**: This statement is also correct. PCR is specifically designed to amplify small amounts of DNA or RNA, making it possible to detect very low concentrations of pathogens in a sample. This is one of the key advantages of using PCR in diagnostics.

3. **Conclusion**:
- Both statements are accurate regarding the capabilities of the PCR technique. Therefore, the correct option is that both statements are correct.

### Final Answer:
Both Statement 1 and Statement 2 are correct. Hence, the correct option is Option 1.
