In an α helix of a protein, there are 3.6 amino acids per complete turn. Each amino acid advances the α helix by 0.15 nm; a complete turn of an α helix is 0.54 nm in length. As shown in Figure 14.6, two α helices of a transcription factor occupy the major groove of the DNA. According to Figure 14.6, estimate the number of amino acids that bind to this region. How many complete turns of the α helices occupy the major groove of DNA?

Question
In an α helix of a protein, there are 3.6 amino
acids per complete turn. Each amino acid advances the α helix
by 0.15 nm; a complete turn of an α helix is 0.54 nm in length.
As shown in Figure 14.6, two α helices of a transcription factor
occupy the major groove of the DNA. According to Figure 14.6,
estimate the number of amino acids that bind to this region. How
many complete turns of the α helices occupy the major groove of
DNA?
