Question

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

Answer 1

single nucleotide polymorphism

Step-by-step 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.
