Question:
Corona virus is a:
Corona virus is a:
Show Hint
+ssRNA = Genome acts directly like mRNA.
Updated On: May 14, 2026
- positive sense single stranded RNA virus
- negative sense single stranded RNA virus
- double stranded RNA virus without segmented genome
- double stranded RNA virus with segmented genome
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Viruses are classified by the type of nucleic acid they contain and their replication strategy (Baltimore classification).
Step 2: Meaning
"Positive sense" means the viral RNA can act directly as messenger RNA (mRNA) to be translated by the host cell's ribosomes.
Step 3: Analysis
Coronaviruses belong to the family *Coronaviridae*. They are enveloped viruses containing a non-segmented, positive-sense single-stranded RNA (+ssRNA) genome. This genome is one of the largest among RNA viruses.
Step 4: Conclusion
Coronaviruses are characterized as +ssRNA viruses. Final Answer: (A)
