1. Protein crystallography is one of the most common methods
used to determine the structure of proteins. However, an emerging
method called “Cryo-EM” is used to determine the structure of the
spike protein.
In your own words, describe what “Cryo-EM” is, and
why it’s a useful for studying protein structures.
2. The spike protein is heavily glycosylated. Briefly describe
what glycosylation is, and why it might be useful for the
virus.
3. Is the spike protein structure a Primary, Secondary,...
