Question

Consider a small protein containing 101 amino acid residues. the protein will have 200 bonds about which rotation can occur. assume that three orientations are possible about each of these bonds.

Answer 1

Small protein containing 101 amino acid residues
the protein will have 200 bonds about which rotation can occur
three orientations are possible about each of these bonds
So, there are 3²⁰⁰ = 2.656 x 10⁹⁵  random-coil conformations will be possible for this protein.
