Explanation:
<span>if Tyler does not eat a diet that includes essential amino acids, his cells will not be able to build some types of essential protein
In order for our body to create different types of protein, it needs the protein template to create requested protein that could only be made by the chains formed by amino acids</span>
The researcher could look for the presence of proteins, because viruses have a envelope (capsid) composed of proteins that involve their genetic material. The capsid may have a helical or icosahedral structure and is extremely regular. Viroids cannot synthesize any type of protein, so differentiation is possible.
