A eukaryotic mutation upstream of a particular gene has been identified that changes the sequence of the TATA box to GATA. How would you predict that this mutation would affect the transcription of this gene

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.
