Choose the incorrect statement of the following

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. Right-handed helical conformation has 3.6 residues per turn with height of 5.4A
  2. The diameter of a typical α helix is about 22 Å, which matches the 22 Å wide and 6–8 Å deep minor groove of B-form DNA

  3. If the α helix lies parallel to the direction of the major groove, the straight α helix can contact 4–6 bp before the bases curve out of the plane of the amino acids in the α helix.

  4. The α helices have rotation of 100 degree per amino acid
