View Answer & Solution

Correct answer · Option A

Single-stranded RNA core surrounded by a protective protein capsid made of capsomeres

Explanation

Figure 2.6(a) shows TMV consisting of a central single-stranded RNA molecule encased in a protein coat called capsid, which is composed of subunit structures termed capsomeres arranged helically.
