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). WebKey Definitions. The observable characteristics of an organism (seen just by looking - like eye colour, or found – like blood type) is called the phenotype. The combination of alleles that control each characteristic is called the genotype. Alleles are often given a lettered code such as Bb or BB or bb to easily represent the genotype ...
