Question

Hepatitis B Virus contains __________.

• A. Double stranded RNA
• B. Single stranded RNA
• C. Single stranded DNA
• D. Partially Double stranded DNA

Hint:

HBV genome is DNA, not RNA, and it is not fully double stranded.

Answer 1

The Correct Option is D

Step 1: Viruses are classified by genome type, and the Hepadnaviridae family, to which HBV belongs, is defined by a DNA genome rather than RNA.

Step 2: The HBV genome is circular but relaxed: one strand runs the full length of the circle, the other is incomplete, so the molecule is neither fully single stranded nor fully double stranded.

Step 3: Once inside a host cell, host and viral enzymes complete the short strand to form a covalently closed circular DNA used for transcription.

So the genome is best described as \[\boxed{\text{Partially Double stranded DNA}}\]
