What could be a possible consequence if a structural gene's TATA box is mutated?
A)The transcriptional start site may not function properly.
B)Transcription may start at a variety of sites.
C)Unusable transcripts may be produced.

E)All of the choices are correct.

Question

Quizplus · Accepted Answer

Mutations in the TATA box can affect the ability of RNA polymerase to bind and initiate transcription at the correct site. This can result in transcription starting at alternative sites, unproductive transcripts being produced, or the preinitiation complex forming at the wrong site. Therefore, all the choices are correct potential consequences of a TATA box mutation.
