Which of the following shows coiled RNA starand and capsomeres?
(1) Polio virus
(2) Tobacco mosaic virus
(3) Measles virus
(2) In TMV RNA is single stranded (ss) helically coiled structure containing about 2130 capsomeres, a basic subunit of capsid (an outer covering of protein that protects the genetic material of a virus).
There are about 16 capsomeres present in each helical turn.
