An experimental study is carried out at Stanford University to understand the transcription of a rare gene involved in neurofibromatosis. Which one of the following is the most common promoter consensus sequence involved in the transcription of DNA in eukaryotes?  

• A. -10 box (also known as the Pribnow box), which is a sequence of six nucleotides (TATAAT) located 10 base pairs upstream of the transcription start site.
• B. -35 box, which is located 35 base pairs upstream of the transcription start site and has a consensus sequence of (TTGACA).
• C. TATA box, which is a sequence of four nucleotides (TATA) located approximately 25-30 base pairs upstream of the transcription start site.
• D. Enhancer elements, which are important in regulating gene expression in eukaryotes.

Answer: (C)
