Difference between virus and viroid is (A) absence of protein coat in viroid, but present in virus. (B) presence of low molecular weight RNA in virus, but absent in viroid (C) Both (A) and (B) (D) None of the above

Identify the correct match of the scientist and their discovery: (a) T.H. Diener : An agent consisting of abnormally folded protein (b) W.M. Stanley : Crystals from viruses contain proteins. (c) M.W. Beijernick : Recognised TMV (d) Ivanowsky : Contagium vivum fluidum

Who discovered an infections agent that was to be a free RNA of low molecular weight, it also lacked protein coat ? This agent caused potato spindle tuber
