You are working in a lab that studies tobacco mosaic virus (TMV). You wish to perform follow up experiments to the Fraenkel-Conrat/Singer experiments

You also use a second TMV strain that you've isolated, called Purp, that causes purple lesions on the leaves, and lacks histidine and methionine in the TMV capsid protein. If you use Purp RNA and HR proteins to create reconstituted viruses, what lesions do you expect will form, and what will the amino acid composition of the capsid protein be? A. Purple lesions, histidine and methionine in the capsid protein B. Purple lesions, no histidine and methionine in the capsid protein C. Streaks on the veins, no histidine and methionine in the capsid protein D. Streaks on the veins, histidine and methionine in the capsid protein
