You are studying a disease that is known to be caused by a single nucleotide change in a single gene, although the effect this change ultimately has on the protein's structure and function is unknown.You have DNA samples from multiple patients that you suspect of having this disease.What is the most efficient way to test the samples for the relevant mutation?
A)Preimplantation genetic diagnosis
B)PCR amplification followed by Sanger DNA sequencing
C)PCR amplification followed by gel electrophoresis
D)High-throughput exome sequencing
E)High-throughput genome sequencing

Question

Quizplus · Accepted Answer

PCR amplification followed by Sanger DNA sequencing is the most efficient method for identifying a specific single nucleotide change in a gene. PCR amplifies the region of interest, and Sanger sequencing provides the precise sequence, allowing for the identification of the specific mutation.
