Why does a noun go with and adverb here?
Now the same technology is allowing genetic engineers to assemble made-to-order viruses, which are essentially genes wrapped in a shell
Hi! My sense is that the adverb is not related to the noun, but to the meaning of the whole sentence; in fact if you move it in another position, for example "which essentially are genes", the meaning doesn't change. Usually an adverb is something that you add to specify a condition in a sentence, it is not something related to a noun like the adjectives.
