All of the following are DNA binding domains found in transcription factors, EXCEPT: (A) Zinc finger, (B) Helix-turn-Helix, (C) Helix-loop-helix, (D) Basic domains
Answer is C. DNA binding domains found in transcription factors DNA binding domains in transcription factors Zinc finger Helix-turn-Helix Basic domains Helix-loop-helix (HLH) Dimerisation domain, Not DNA-binding domain. Proteins with HLH also contains a separate DNA binding domain made up of basic amino acids. E.g. Hypoxia-inducible factor (HIF) MyoD MITF (Microphthalmia-associated transcription factor)
