The specific recognition of the lac operator sequence in the DNA occurs largely though [[Hydrogen bonds|hydrogen bonds]]. <scene name='Lac_repressor/1osl_14_1l1m_9_morph_hbonds/1'>Formation of hydrogen bonds that recognize the operator sequence</scene> is illustrated in this rendering of the morph. Shown are hydrogen bonds involving Arg22.N-eta2 and Tyr18.OH interacting with DNA base oxygens in the major groove, and Ala53.O interacting with a DNA base nitrogen in the minor groove. (Not all of the relevant hydrogen bonds are shown; see [[Lac repressor morph methods|Methods]].) {{Template:Button Toggle Animation}} | The specific recognition of the lac operator sequence in the DNA occurs largely though [[Hydrogen bonds|hydrogen bonds]]. <scene name='Lac_repressor/1osl_14_1l1m_9_morph_hbonds/1'>Formation of hydrogen bonds that recognize the operator sequence</scene> is illustrated in this rendering of the morph.
