SNP is an acronym for:

A. simple Northern probe

B. sample in situ probe

C. simple nucleotide probe

D. single nucleotide polymorphism polypeptide

E. sequence normal

single nucleotide polymorphism

Explanation:

A SNP (above) is a mutation in DNA at exactly one nucleotide (A, T, C, or G) that is present in at least 1% of the population.

For instance, let's say a certain protein relies on the sequence - TTG - at a certain position in a gene. If the sequence - ATG - is seen in that exact position in the gene (the A residue replacing the first T residue) in at least one percent of the population, this would be a SNP. If this replacement were in less than one percent of the population, it would just be a mutation.
