Question

Name and describe briefly two common techniques that are used in the laboratory to identify genetic and infectious diseases? [2 marks each].

Write maximum 5-10-line response.

Answer 1

The polymerase chain reaction (PCR) is an example of this type of test. The PCR technique is used to produce many copies of a gene from a microorganism, making the microorganism much easier to identify. Each genetic test is specific to only one specific microorganism.
