The class __________ DNA-binding motif is common to many DNA-binding proteins.

Question

Quizplus · Accepted Answer

The helix-turn-helix DNA-binding motif is found in many DNA-binding proteins, including transcription factors. This motif is characterized by two alpha helices connected by a turn, with the first helix binding to the DNA and the second helix providing stability to the protein-DNA complex. Stem-and-loop, inverted-repeat, and hairpin motifs are not typically used for DNA binding, and the double-helix is the overall structure of DNA itself, not a motif found in DNA-binding proteins.
