Thank you for your question! This is what makes viruses so tricky. Coronavirus, like most others, carries its genome (in this case RNA) inside of their outer protein structure. Once they latch on, they inject the RNA directly into the cell. This essentially puts RNA in immediate contact with host ribosomes to translate it into viral proteins as well as additional RNA that will become a part of the new virions. Viruses are masterful at this, which is why we have such a hard time fighting them. Thanks again!
