There are four amino acid residues between each turn of an alpha helix, because O hydrogen bonding between the carbonyl and amine groups is more stable at this distance. O amino acid residues need a certain amount of distance between then during the turn. O the polar amino acids are more attractive to the peptide bond at this distance. O None of the choices are correct.
