Question

A pseudovirus is characterized by which of the following?
Options
A It contains viral DNA and replicates efficiently within host cells.
B It is an artificially engineered viral particle that lacks pathogenic genetic material for replication and contains host DNA.
Correct Answer
C It is a defective virus that relies on a helper virus to complete its life cycle.
D It is a single-stranded RNA molecule that causes disease in plants.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text describes pseudoviruses as 'artificially engineered viral particle that mimics the structure and entry mechanism of a real virus but lacks the pathogenic genetic material required to replicate. Pseudoviruses contain host DNA instead of viral DNA; they infect the host cell but don't replicate.'

Hint

Pseudoviruses are tools for research, designed to infect but not to cause disease through replication of their own genetic material.
