may be you are right. but when DNA or RNA is in A form, the melting point increases. i think, it indicates the compactness.

George was right. Viruses are not visible through light microscope. I'd try to grow it on an agar plate (if possible, on MH) containing antifungal agents.

dont know about any catalyst other than those found in living organism. but u can use oxidizing agent (KMnO4+sulfuric acid) or chlorine. It'll produce O2.

Re: dsRNA

dsRNA attains A form, that would be too much compact and could be almost inaccessable for the polymerase withiut proper helicase. you couldn't have the RNAi defence system and rna is much more mutation prone. donno whether im right or wrong!
