Practice: An alpha helix is a protein folding pattern that is classified under which of the following protein structures?

Practice: A protein with 3000+ amino acids obtained a mutation that caused an amino acid change in a region of the protein that does not normally interact with other molecules. What type of effect could this cause?

Practice: he entire sequence of the protein is used to form the protein’s structure.

Practice: A coiled coil and an alpha helix are two terms for the same structure.
