Helix three of each repressor monomer binds to the recognition sequence in the major groove. Specific glutamines in the repressor protein make hydrogen bonds to specific bases in DNA. Identify the specific bases in this interaction. cytosine 2, adenine 3, adenine 4 guanine 1, adenine 2, cytosine 4 adenine 1, guanine 2, thymine 4 adenine 1, adenine 3, adenine 4 adenine 1, cytosine 2, adenine 3
