Which consensus sequence located approximately 25 to 30 base pairs upstream of transcription serves as a core promoter in eukaryotes?
Answer and explanation
Correct answer: B. TATA box
The TATA box (TATAAA) is the core promoter element located around -25 to -30 bp in eukaryotes, bound by TBP (TATA-binding protein). The Pribnow box (-10) and Shine-Dalgarno sequence are bacterial elements; the Kozak sequence surrounds the start codon in mRNA.
