One chain contains residues numbered 1-12 in sequence CGCG AATT CGCG. The other chain contains residues numbered 13-24 with an identical (antiparallel) sequence. | One chain contains residues numbered 1-12 in sequence CGCG AATT CGCG.

Theoretical models typically represent idealized DNA conformation, whereas real DNA may have various irregularities including kinks and bends (see examples bound to the [[Lac repressor]]). | Theoretical models typically represent idealized DNA conformation, whereas real DNA may have various irregularities including kinks and bends (see examples bound to the [[Lac repressor]]). There are plenty of empirical models for DNA, the first having become available in the 1970's and 80's (see [[#History of DNA Structure|above]]). In May, 2012, the [[Protein Data Bank]] contains nearly 4,000 entries containing DNA. Over 1,300 contain only DNA, while over 2,000 contain protein-DNA complexes. Over 100 entries contain protein, DNA and [[RNA]], and over 100 contain DNA/RNA hybrid molecules. | ||
