Properties of the alpha-helix. 1  The structure repeats itself every 5.4 Angstroms along the helix axis, ie we say that the alpha-helix has a pitch of 5.4 Angstroms. Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns.
Properties of nucleic acids are as follows:Nucleic acids (DNA and RNA) are long polymers made of repeating units of nucleotides. Nucleotide units are made of phosphate-sugar-nitrogenous base units.The nitrogenous bases found in DNA are adenine, guanine, cytosine and thymine.ypes of Nucleic Acids. 1  DNA is one of the macromolecules, they are essential to all living forms. 2  Deoxyribonucleic acid contains the genetic information, it is used in the development and functioning of all living organisms. 3  The DNA segments carry genetic information are called the genes.
