DSpecific antigen of virus

Correct Answer
CRNA of virus
Model Answer
A reverse transcription-polymerase chain reaction (RT-PCR) test is done to detect the presence of specific genetic material in any pathogen, including a virus.
In recent times, this process has been used to detect COVID-19, Ebola virus and Zika virus.
Specimen for the test is collected from the throat and nose.
The genetic material of coronavirus (SARS-CoV-2) or COVID-19 virus comprises only RNA.
It means that the coronavirus relies on infiltrating healthy cells to multiply and survive.
Once inside the cell, the virus uses its RNA to take control of and re-programme the cells and turn them into virus-making factories.
Hence, option C is correct.
Additional Information
RNA is generally a one-strand molecule that copies transcribe and transmits parts of the genetic code to proteins so that they can synthesize and carry out functions that keep organisms alive and developing.
Different variations of RNA are responsible for copying, transcribing and transmitting.
