1
Q
What are the known frequencies of various amino acid residues in a helix used for?
A
To predict the secondary structure based on the primary sequence alone.
Example sentence: The known frequencies of various amino acid residues in a helices are used to predict the secondary structure based on the primary sequence alone.

Q
What is a common structure in DNA-binding proteins called?
A
Leucine zipper.
Example sentence: Some proteins contain a few short regions of a 310 helix. Like the a helix, the 310 helix is right-handed.
3
Q
What do the ends of the helices in a leucine zipper form?
A
The DNA-binding region of the protein.
Example sentence: The ends of the helices form the DNA-binding region of the protein.
