The process that converts the chain of amino acids into a finished protein is called "protein folding", and yes, other proteins are involved, but the protein also influences its own folding to some degree: some parts want to be together, others want to be apart, etc. Those aid proteins, called chaperones, too, are created by the same process they are part of. Viruses use the assembly proteins of the host cell, but sometimes they bring their own proteins that are involved in some parts of the process (but not all of it). For the cell, there is an obvious chicken/egg problem here: if it needs such a process to turn RNA into chaperone proteins, and in order to clone RNA you need proteins, too, then what came first, the protein or the RNA? The process of how life evolved in this early stage is very poorly understood, but it is believed that everything evolved from RNA (RNA world hypothesis). https://en.wikipedia.org/wiki/Protein_folding https://en.wikipedia.org/wiki/Protein_folding
