Answer:
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.
 
        
             
        
        
        
 <span>DNA contains the code for all an organism's protein. Since many of the organism's structures, processes, and growth depend on protein the DNA is central to the well being of all organisms. In eukaryotes, the DNA is locked up in the nucleus. The area of the cell where proteins are made is in the cytosol (ribosomes). In order for the protein to be made the DNA has to produce a copy of the blueprint m-RNA. This messenger RNA will take the code to the ribosome. The process by which m-RNA is made is called transcription. A-U, C-G base pairing rules. Once on the ribosome another RNA comes into play t-RNA. This is called transfer RNA. Here it will take an amino acid and place it in the correct order to produce the desired protein. This is called translation. It begins with a start co don AUG. and ends with a stop codon. The protein will then go to the Golgi apparatus and be formed into its final shape.

If this is a true or false question, the answer would be true. Hemodilution means an increase in blood plasma that would result in a dilution of the blood's cellular content.Hope this is the answer and would be of help.
