Question

Given below is the diagram of a virus. Identify the option with correct labelling of A, B and C.

• A. A-RNA, B-Capsomere, C-Bacteriophage
• B. A-DNA, B-Capsid, C-Bacteriophage
• C. A-RNA, B-Capsid, C-Tobacco mosaic virus
• D. A-RNA, B-Capsid, C-Bacteriophage

Answer 1

The correct option is C A-RNA, B-Capsid, C-Tobacco mosaic virus

Tobacco mosaic virus is a single-stranded RNA virus in the Tobamovirus genus. This is the first pathogen to be identified as a virus. This virus appears rod-like. The capsid is coat protein.The coat protein assembles into the rod-like helical structure wrapping around RNA. It forms a hairpin loop structure. Hence, A-RNA, B-Capsid, C-Tobacco mosaic virus.
