SNP-Chips are Used ____

Question

SNP-chips are used ____.  
A) to sequence DNA.
B) in DNA profiling
C) for full genome sequencing
D) in PCR
E) with short tandem repeat profiling

Accepted Answer

SNP-chips are used in DNA profiling to detect single nucleotide polymorphisms (SNPs) which are variations in a single base pair in the DNA sequence. These variations can be used to distinguish between individuals and identify genetic markers associated with certain traits or diseases. SNP-chips do not sequence the entire genome, but instead focus on specific regions known to contain SNPs. PCR and short tandem repeat profiling are other methods used in DNA profiling, but they do not involve the use of SNP-chips. Full genome sequencing involves sequencing the entire DNA of an individual, which is not the primary function of SNP-chips.
