The sequence is a hypothetical segment of a DNA with an indicated mutation represented by an arrow. The sequence is five prime T T G T G C G G A T A G G T C C T highlighted A T T T A A C three prime. The arrow is pointing to the highlighted A. The exon part of the sequence is T T G T G C G G A T A G. The intron part of the sequence is G T C C T highlighted A T T T A A C. What is the outcome of this mutation with regard to the ultimate protein that will form from this sequence? This is a nonsense mutation. The protein will be truncated early and likely be nonfunctional. An alternative splice site is formed. Two proteins of different lengths will be produced. The corresponding amino acid is altered. The protein will be changed. Nothing. This is a silent mutation. The protein will be unchanged.

Explanation:

Mutation is defined as a change in nucleotide sequence of a gene. When a single nucleotide is inserted,deleted or substituted in a DNA sequence, then the resulting mutation is classified as point mutation.

A gene contains two region- intron region and exon region.

The region that codes for a particular protein is called the exon and the region that separates two exons  and does not code for any protein is called the intron.

Most of the point mutations in the intron region are silent except if it is located at the splice site recognition sequence.

In the given situation the mutation is in the middle of the intron region so there is no chance of it being a splice site recognition sequence.  Hence the protein will remain unchanged.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
