Answer:
The forensic analysis technique that identifies the difference between a single nucleotide at a specific location is called SNP analysis or SNP genotyping.
Step-by-step explanation:
The forensic analysis technique that identifies the difference between a single nucleotide at a specific location is called SNP analysis or SNP genotyping.
SNPs (single nucleotide polymorphisms) are variations in the DNA sequence that occur when a single nucleotide (A, T, C, or G) in the genome differs among individuals. SNP analysis involves comparing the DNA sequence of an individual with a reference genome or another individual's DNA sample to identify the SNPs present at specific locations in the genome.
SNP analysis is a powerful forensic tool that can be used for a variety of purposes, including paternity testing, identification of genetic disorders, and identification of suspects in criminal investigations. By analyzing the SNPs present in a DNA sample, forensic scientists can determine whether two samples are from the same individual or related individuals, or whether a sample matches a suspect's DNA profile.
