Question

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

Answer 1

Explanation:

The technique of polymerse chain reaction (PCR) has been applied to detect HIV in suspected AIDS patients and to detect mutations in genes in suspected cancer patients.

Answer 2

Explanation:

                             Hi Friend !!!

Statement 1 and 2 are true and 2 is the correct explanation of 1

As you know that PCR is a device which can be used  to detect a disease early b amplifying the nucleic acid ( mainly desired fragment) for 30 cycle to make billions of copy.

So even if the presence of disease is small, it will be amplified and thus we can detect the disease
