When students first look at an amino acid sequence, a long string of confusing letters, they often think those letters are part of a chain like an uncooked spaghetti noodle.  Stiff and unbending, with one end far from the other. Molecular modeling apps let us demonstrate that proteins are a bit more like fresh pasta. If we apply rainbow colors (Red Orange Yellow Blue Indigo Violet) to a protein chain, we can ... Read more
