State

A eukaryotic promoter for RNA polymerase II contains a TATA box, an AT-rich sequence 25 to 35 base pairs upstream of the start site.

Show

A TATA box's sequence, resembling TATAAA, marks where the initiation complex assembles for a gene.

Watch for

A eukaryotic promoter is far larger than a prokaryotic one — the TATA box is one element within it, not the whole promoter.
