Diagram of dna
DNA 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). The pair of chain… WebThe three models for DNA replication There were three basic models for DNA replication that had been proposed by the scientific community after the discovery of DNA's structure. These models are illustrated in the …

WebThe structure of DNA, as represented in Watson and Crick's model, is a double-stranded, antiparallel, right-handed helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together. WebYour DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix).
