Many promoter regions in genes transcribed by eukaryotic RNA polymerase II do not contain a TATA box sequence. However, all three eukaryotic polymerases require TBP for transcription initiation regardless of the presence of a TATA box in the promoter region. What hypothesis might explain why TBP is necessary for transcription from TATA-less promoters?

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate
