KCET · BIOLOGY · STD 12 - 10. Biotechnology and Its Applications
Now-a-days, the early diagnosis of bacterial or viral infection in human is possible using.
- A CT Scan
- B Serum analyser
- C DNA sequencer
- D PCR
Answer & Solution
Correct Answer
(D) PCR
Step-by-step Solution
Detailed explanation
(D) PCR,
Polymerase chain reaction (PCR) is a technique that permits diagnostic tests to be performed on small amounts of DNA. Besides, the use of PCR technique allows the detection of presence of disease-casuing bacteria or viruses much before the disease manifests itself, thereby allowing early detection and treatment. PCR is currently used to detect mutation in genes in patients suspected to be suffering from cancer and to detect HIV in patients suspected of AIDS.
