1) What kind of amino acid side chains would you expect to find out folded on the interior of a globular protein? What type of experimental evidence supports this claim?
2) Which amino acid lacks a stereoisomer and which consists of more than one asymmetric carbon?
3) What property of the DNA double helix permits us to state that the recognition site for a restriction endonuclease like BamHI (GGATCC) is a structural palindrome?
4) What general types of quaternary structure do we expect to find out for the restriction endonuclease PstI, which as well recognizes a palindromic structure?
