Question

Quizplus · Accepted Answer

The TATA box is not a shape in a regulatory protein but rather a specific DNA sequence (TATAAAA) which is recognized by the TATA-binding protein (TBP) to initiate transcription. The other choices (zinc finger, helix-turn-helix, homeodomain, leucine zipper) are all examples of structural motifs found in regulatory proteins that are involved in DNA binding.
