WebIt is the second most common form of DNA, also called A-DNA. It has DNA of right-helical sense. A-DNA structure forms under normal physiological conditions like 75% relative humidity and the presence of sodium, potassium, and caesium ions. The coiling of A-DNA is in a right-handed fashion. It is metastable, i.e. easily turns into a D-form. WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

WebThe polypeptide chain made by the ribosome also has directionality; one end has a free amino group and the other end of the chain has a free carboxyl group. These are called the N-terminus and the C-terminus, respectively. New amino acids are added only to a free carboxyl end, so polypeptide chains grow from the N-terminus to the C-terminus. food town stores in houston
