Question

A model of the upstream region of a gene is shown. RNA polymerase typically binds here before transcription begins. A mutation in the TATA box region of the promoter would have which effect?

Answer 1

dd RNA polymerase will not bind to the promoter in a stable configuration, and transcription will decrease.

Answer 2

The mutation could cause serious damage in the replication process.

Step-by-step explanation:

The TATA box is a DNA region that indicates the point where, processes like replication can begin. The mutation of this could cause that replication never begins, and therefore, protein synthesis is stopped. This severe complication would lead the cell to death in a short amount of time, for example.
