D) It is the recognition site for ribosomal binding during transcription.

Question

Quizplus · Accepted Answer

The TATA box is a DNA sequence found in the promoter region of genes in eukaryotes and some prokaryotes. It is crucial for the initiation of transcription because it serves as the binding site for the TATA-binding protein (TBP), a component of the transcription factor IID (TFIID). This binding is essential for the recruitment of other transcription factors and RNA polymerase II to the promoter, initiating transcription. The TATA box does not directly involve in setting the reading frame of mRNA during translation or in ribosomal binding during translation or transcription.
