core promoter elements
Na
Na
the dna double helix biopolymer of nucleic acid, held together by nucleotides which base pair together. in b-dna, the most common double helical structure found in nature, the double helix is right-handed with about 10–10.5 base pairs per turn. the double helix structure of dna contains a "major groove" and "minor groove". in b-dna the major groove is wider than the minor groove. given the difference in widths of the major groove and minor groove, many proteins which bind to b-dna do so through the wider major groove.
