- Adenovirus
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Viruses can be classified based on the presence or absence of a lipid envelope:
• Enveloped viruses: Have a lipid membrane derived from host cells
• Non-enveloped viruses: Lack this membrane
Step 1: Analyzing each virus.
• Dengue virus: Enveloped RNA virus → Correct.
• Polio virus: Non-enveloped RNA virus → Incorrect.
• Foot and mouth disease virus: Non-enveloped RNA virus → Incorrect.
• Adenovirus: Non-enveloped DNA virus → Incorrect.
Step 2: Selecting the correct answer.
Thus, Dengue virus is an enveloped virus.
• Enveloped viruses: Have a lipid membrane derived from host cells
• Non-enveloped viruses: Lack this membrane
Step 1: Analyzing each virus.
• Dengue virus: Enveloped RNA virus → Correct.
• Polio virus: Non-enveloped RNA virus → Incorrect.
• Foot and mouth disease virus: Non-enveloped RNA virus → Incorrect.
• Adenovirus: Non-enveloped DNA virus → Incorrect.
Step 2: Selecting the correct answer.
Thus, Dengue virus is an enveloped virus.
