Which of the Following Sequences Indicates the Promoter Region of a Gene

Question

Which of the following sequences indicates the promoter region of a gene?
A) CAAT
B) UAAG
C) CTTT
D) ACAT
E) TAAC

Accepted Answer

The CAAT box is a common promoter element found in eukaryotic genes. It is typically located about 70 to 80 base pairs upstream of the transcription start site and is recognized by transcription factors that help recruit RNA polymerase to the promoter. The other sequences listed are not typically found in promoter regions.
