Question:

Which among the following is not true about PCR ?

Options:

PCR technique serve the purpose of early diagnosis.

PCR is used to detect HIV in suspected AIDS patients.

PCR is used to detect mutations in genes in suspected cancer patients too .

PCR is not used to detect HIV in AIDS patients.

Correct Answer:

PCR is not used to detect HIV in AIDS patients.

Explanation:

The correct answer is Option 4- PCR is not used to detect HIV in AIDS patients.

Polymerase Chain Reaction technique serve the purpose of early diagnosis.However, very low concentration of a bacteria or virus (at a time when the symptoms of the disease are not yet visible) can be detected by amplification of their nucleic acid by PCR. PCR is now routinely used to detect HIV in suspected AIDS patients. It is being used to detect mutations in genes in suspected cancer patients too. It is a powerful techqnique to identify many other genetic disorders.

PCR is not used to detect HIV in AIDS patients. This statement is false. PCR (Polymerase Chain Reaction) is indeed used as a sensitive and specific method for detecting the presence of HIV (Human Immunodeficiency Virus) in AIDS patients. PCR can amplify and detect viral nucleic acids, making it valuable for the diagnosis of HIV infection. The other statements are true, as PCR is commonly used for early diagnosis, detecting HIV in AIDS patients, and identifying mutations in genes in suspected cancer patients.
