Solution
The correct option is D TMV has a doubled stranded RNA.
TMV is a positive sense single-stranded RNA virus which infects tobacco and other members of the family Solanaceae. TMV is a simple rod-shaped helical virus consisting of centrally located single-stranded RNA that is enveloped by a protein coat. The rod is considered to be 3,000 Å in length and about 180 Å in diameter. The ssRNA is little more in length which is about 3300 Å so it slightly protruding from one end of the rod. The RNA molecule consists of about 7300 nucleotides and the molecular weight of the RNA molecule is about 25,000 dalton. So, the correct answer is 'TMV has a doubled stranded RNA'.
