A change in which a single base in the DNA differs from the usual base at that position. Abbreviated SNP and pronounced snip. Millions of SNP's have been cataloged in the human genome. Some SNPs are responsible for disease such as the SNP responsible for sickle cell disease. Many other SNPs are normal variations in the genome.

The most common type of change in DNA (molecules inside cells that carry genetic information). Single nucleotide polymorphisms occur when a single nucleotide (building block of DNA) is replaced with a [..]

Single base variation at a chromosomal locus which exists stably within populations (typically defined as each variant form being present in at least 1-2% of individuals). After [8]

SNP

A single nucleotide polymorphism (SNP) is a change in your DNA code at a specific point.

A single nucleotide polymorphism, or SNP, is a single base-pair difference in the DNA sequence of individual members of a species; not necessarily a pathological mutation, but commonly studied as a co [..]

A single base pair of DNA that is polymorphic (has alternate alleles) with respect to a population.

A site on the DNA

A site on the DNA at which the base sequence differs among individuals. (The abbreviation is pronounced "snip.")

The most common type of change in DNA (molecules inside cells that carry genetic information). Single nucleotide polymorphisms occur when a single nucleotide (building block of DNA) is replaced with another. These changes may cause disease, and may affect how a person reacts to bacteria, viruses, drugs, and other substances. Also called SNP.

A genetic variation based on a single ‘letter’ difference in the genetic code.

Individual differences at a single nucleotide of DNA. This genotypic difference can cause a phenotypic difference in hair colour, height or response to a drug, depending on the gene.

The human genome is the entire sequence of genetic information contained within our DNA. This sequence is made up of strings of molecules called nucleotides, which are the building blocks of DNA. There are four nucleotides, called A,C, T and G.

Inter-individual variations in the genetic code at the level of one nucleotide.

A change in which a single base in the DNA differs from the usual base at that position.

A single nucleotide variation in a genetic sequence that occurs at appreciable frequency in the Population.

The most common type of change in DNA (molecules inside cells that carry genetic information). Single nucleotide polymorphisms occur when a single nucleotide (building block of DNA) is replaced with another. These changes may cause disease, and may affect how a person reacts to bacteria, viruses, drugs, and other substances. Also called SNP.

Variation in a single base in the genetic code between different individuals of the same species.

A difference of one nucleotide of a DNA sequence.

Scattered single-base pair variations within the genetic code of the individuals of a population. SNPs determine ways that subpopulations within a species differ and provide information about variations of protein expression.

A precise position along a chromosome where the DNA of different people may vary. Generally two alternate alleles are found at a particular SNP. At least 2,000,000 SNPs are now known and there may be [..]

Variation in the identity of a nucleotide base pair at a single position in a DNA sequence, within or among populations of a species.

Variation in the nucleotide allele at a certain nucleotide position in the human genome. When the change occurs it is called a polymorphism, and polymorphisms accumulate over time. A polymorphism can [..]
