Question

Q. Which of the following statements is/are correct about Coronavirus (SARS-CoV-2)?

Select the correct code from the options given below:

• A. 1 only
• B. 2 only
• C. Both 1 and 2
• D. None of the above

Answer 1

The correct option is D None of the above

Explanation:

• Statement 1 is incorrect. Coronavirus (SARS-CoV-2) contains only RNA. It means that the virus relies on infiltrating healthy cells to multiply and survive. Once inside the cell, the virus uses its genetic code — RNA in the case of the COVID-19 virus — to take control of and ‘reprogramme’ the cells, turning them into virus-making factories.
• Statement 2 is incorrect. RT-PCR test which is used to detect COVID uses reverse transcription which converts RNA into DNA. For a virus like the COVID-19 virus to be detected early in the body using real-time RT–PCR, scientists need to convert the RNA to DNA. This is a process called reverse transcriptionAnaemia They do this because only DNA can be copied — or amplified — which is a key part of the real-time RT–PCR process for detecting viruses.
