Reaction that changes a single base pair in DNA.

A single nucleotide change that substitutes one nucleotide for another. A point mutation in the coding sequence of a gene affects a single codon, and often allows expression of an intact but nonfunctional or partially functional protein.

(French : mutation ponctuelle) Mutation interesting only one base. Addition or deletion are mutation mechanisms.

Change of a single nucleotide in DNA, especially in a region coding for protein; can result in formation of a codon specifying a different amino acid or a stop codon, or a shift in the reading frame. [..]

An alteration in a DNA sequence caused by the substitution of a single nucleotide for another nucleotide.

A mutation that can be mapped to one specific site within a locus. A small mutation that consists of the replacement (transition or transversion); addition; or deletion ( frameshift) of one or a few b [..]

The substitution of one nucleotide for another nucleotide amino acid on a gene.

A single nucleotide base change in DNA. For example, a point mutation is the cause of sickle cell disease.

A point mutation is when a single base pair is altered. Point mutations can have one of three effects. First, the base substitution can be a silent mutation where the altered codon corresponds to the same amino acid. Second, the base substitution can be a missense mutation where the altered codon corresponds to a different amino acid. Or third, the [..]

A change in a single nucleotide in a DNA sequence. See also transition, transversion.

A single nucleotide substitution within a gene; there may be several point mutations within a single gene. Point mutations do not lead to a shift in reading frames, thus at most cause only a single am [..]

an elimination, alteration, or insertion of a single base pair, causing an alteration in the DNA chain.

A Mutation caused by the substitution of one nucleotide for another. This results in the DNA molecule having a change in a single Base Pair.

A mutation caused by the substitution of one nucleotide for another. This results in the DNA molecule having a change in a single base pair.

A mutation caused by a substitution of one base pair for another.

a change in the DNA involving very few nucleotides.

A single base change.

A mutation that maps to a specific gene locus; in a molecular context, usually a change of a single base pair.

A type of mutation in which a single nucleotide is changed to one of the other three possible nucleotides.

A change in a gene at a single nucleotide pair.

A mutation

gene mutation in which a single base pair in DNA has been changed
