The TATA box is
- A
An rRNA element ~25 nt within the small subunit, where initiation factors bind to begin assembly of the ribosome complex
- Bcheck_circle
A DNA element ~25 bp upstream of the start of many eukaryotic genes, where TFIID binds to begin assembly of the transcription complex
- C
An mRNA hairpin element ~25 nt downstream of the start codon, where eIF4E binds to begin assembly of the translation complex
- D
A protein motif ~25 aa upstream of an active site, where chaperones bind to begin folding of the polypeptide complex
Explanation
The TATA box helps position RNA Polymerase II at the right place to start transcription.
