E All the above Correct Answer Incorrect Answer

Solution

Ø  The technique of polymerase chain reaction (PCR) is used to detect infectious organisms as well as mutations in specific genes. Ø  PCR can be used to directly analyse the virus DNA in the case of diseases like AIDS, and it is more specific than the standardised detection done by ELISA. Ø  Used to compare a person's DNA to a specific sample, such as blood collected at a crime scene. Ø  The PCR may amplify DNA, and by utilising a specific marker, the precise gene that causes the disease can be identified.
