Which of the following hepatitis-causing virus contains DNA as nucleic acid?
Updated On: Jul 12, 2024
- (A) HAV
- (B) HBV
- (C) HDV
- (D) HEV
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Explanation:
Hepatitis B virus (HBV) is a member of the Hepadnaviridae family. It is a partially double-stranded DNA virus with a size of 3.2 kb. It has an incomplete positive strand, but the complete negative-strand has four overlapping genes, as mentioned subsequently.Hepatitis B virus (HBV), a major worldwide infectious and cancer-promoting agent contains a DNA genome of 3226 base pairs that replicates by a reverse transcriptase via an RNA intermediate.Hence, the correct option is (B).
