WebThe major groove occurs where the backbones are far apart, the minor groove occurs where they are close together. The grooves twist around the molecule on opposite sides. Certain proteins bind to DNA to alter its structure or to regulate transcription (copying DNA to RNA) or replication (copying DNA to DNA). WebSep 1, 2006 · A number of small molecules bind directly and selectively to DNA, acting as chemotherapeutic agents by inhibiting replication, transcription or topoisomerase activity. Two common binding modes for these small molecules are intercalation or groove-binding. Intercalation results from insertion of a planar aromatic substituent between DNA base …

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). triphasic abihttp://pubs.sciepub.com/bb/2/1/1/ triphasic adhWebHelix-turn-helix is a DNA-binding protein (DBP). The helix-turn-helix (HTH) is a major structural motif capable of binding DNA.Each monomer incorporates two α helices, joined by a short strand of amino acids, that bind to the major groove of DNA.The HTH motif occurs in many proteins that regulate gene expression.It should not be confused with the … triphasia trifoliaWebIn molecular biology, a histone octamer is the eight-protein complex found at the center of a nucleosome core particle.It consists of two copies of each of the four core histone proteins (H2A, H2B, H3, and H4).The octamer assembles when a tetramer, containing two copies of H3 and two of H4, complexes with two H2A/H2B dimers.Each histone has both an N … triphasic anaphylaxisWebDNA-binding proteins are proteins that have DNA-binding domains and thus have a specific or general affinity for single- or double-stranded DNA.
