Rapid antigen test and RT-PCR are the two diagnosis test for Covid-19 virus. PCR, a molecular diagnostic, tool stands for
- Polymerase chain reaction
- Polymerase chain reagent
- Physiological chain reaction
- Physiological chain reagent
The Correct Option is A
Approach Solution - 1
The question asks for the full form of the acronym PCR, which is mentioned alongside Rapid Antigen Test and RT-PCR as diagnostic tools for COVID-19.
PCR is a foundational technique in molecular biology used to amplify (make many copies of) a specific segment of DNA. RT-PCR (Reverse Transcription PCR) is a variation used for RNA viruses like SARS-CoV-2 (the virus causing COVID-19), where the viral RNA is first reverse transcribed into DNA, which is then amplified by PCR.
The acronym PCR stands for:
- P - Polymerase: Refers to the enzyme (DNA polymerase, often Taq polymerase) that synthesizes new DNA strands.
- C - Chain: Refers to the repetitive, cyclical nature of the process where the products of one cycle serve as templates for the next, leading to exponential amplification.
- R - Reaction: Refers to the biochemical process occurring in the test tube.
Therefore, PCR stands for Polymerase Chain Reaction.
Comparing this to the options:
- Polymerase chain reaction - Correct.
- Polymerase chain reagent - Incorrect. 'R' stands for Reaction.
- Physiological chain reaction - Incorrect. 'P' stands for Polymerase.
- Physiological chain reagent - Incorrect. 'P' stands for Polymerase and 'R' stands for Reaction.
