Question
The normal polypeptide A+ contains 150 amino acids. The mutant polypeptide A- has an additional 25 amino acids inserted between the two amino acids in positions 35 and 36 of the normal polypeptide, and contains a total of 175 amino acids. Which of the following mutations may account for this change in the structure of the resulting polypeptide?
A nonsense mutation
A sense mutation caused by a base substitution
Duplication of one of the introns of the gene
Duplication of one of the exons of the gene
A sense mutation caused by a base insertion in the last exon
A.A nonsense mutation
B.A sense mutation caused by a base substitution
C.Duplication of one of the introns of the gene
D.Duplication of one of the exons of the gene
E.A sense mutation caused by a base insertion in the last exon
Explanation / Answer
Which of the following mutations may account for this change in the structure of the resulting polypeptide?
