Question

Most sensitive technique to detect malignant cells in non-Hodgkin's lymphoma is:
A. Polymerase chain reaction
B. Gene therapy   
C. Stem cell therapy
D. None of the above

Answer 1

Hint: Lymphomas are cancers of a certain type of white blood cells referred to as lymphocytes. These cells help to fight infections. Lymphomas can develop from either T or B lymphocytes, the two major types of lymphocytes. Non-Hodgkin lymphomas are more than 50 various diseases that involve T- cell or B-cell lymphocytes.
Complete Step-by-step answer:
The polymerase chain reaction is a laboratory method for rapidly generating (amplifying) millions to billions of copies of a specific segment of DNA. The most sensitive method for detecting malignant cells in non- Hodgkin's lymphoma is a polymerase chain reaction. Recently, PCR is used in the detection of HIV (Virus of AIDS).
Gene therapy is a medical method that prevents or treats disease by correcting the underlying genetic problem. Gene therapy methods allow doctors to treat a disorder by altering a person's genetic makeup rather than using drugs or surgery.
Stem cell therapy is also commonly known as regenerative medicine. It promotes the repair response of diseased, dysfunctional, or injured tissue using stem cells or their derivatives. These cells have strong healing power. They can develop into any type of cell. Stem cells are unique human cells that can distinguish into a variety of cell types, which range from muscle cells to brain cells.
Therefore the correct answer is Option A.
Note: The polymerase chain reaction was initially developed in 1983 by the American biochemist Kary Mullis. He won the Nobel Prize in Chemistry in 1993 for his pioneering work. PCR is used in molecular biology to create several copies of (amplify) small parts of DNA or a gene.
