Question
Which of the following statements are true about SARS-CoV-2?SELECT ALL THAT APPLYThe virus attaches to host cells via its neuraminidase spike.The genome of SARS-CoV-2 undergoes mutations.SARS-CoV-2 is a naked virus.SARS-CoV-2 has an antisense RNA genome.The strain designation of SARS-CoV-2 is H1N1.SARS-CoV-2 causes Covid-19.
Solution
The following statements are true about SARS-CoV-2:
-
The genome of SARS-CoV-2 undergoes mutations: This is true. Like all viruses, SARS-CoV-2 mutates over time as it replicates within a host. These mutations can lead to new variants of the virus.
-
SARS-CoV-2 causes Covid-19: This is true. SARS-CoV-2 is the virus that causes the disease known as Covid-19.
The following statements are false about SARS-CoV-2:
-
The virus attaches to host cells via its neuraminidase spike: This is false. SARS-CoV-2 uses its spike protein, not neuraminidase, to attach to host cells.
-
SARS-CoV-2 is a naked virus: This is false. SARS-CoV-2 is an enveloped virus, which means it is surrounded by a lipid bilayer.
-
SARS-CoV-2 has an antisense RNA genome: This is false. SARS-CoV-2 has a positive-sense single-stranded RNA genome.
-
The strain designation of SARS-CoV-2 is H1N1: This is false. H1N1 is a strain of influenza virus, not SARS-CoV-2.
