Mutation in a sentence

A germline mutation gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in every cell.

I-mutation in Old English The vowels and diphthongs of proto-Old English prior to i-mutation (in black) and how they generally changed under i-mutation (in red).

Mutation rates further Mutation rates vary substantially across species, and the evolutionary forces that generally determine mutation is the subject of ongoing investigation.

We say that the mutation is recessive because the organism will exhibit the wild type phenotype (ordinary trait) unless both chromosomes of a pair have the mutation ( homozygous mutation).

Feline geneticist Leslie Lyons, from the University of Missouri, first identified the mutation in Siamese cats, and has stated that the Himalayan mutation naturally occurs in South Asian domestic felines.

If someone has a mutation then his or her children each have a 50 percent chance of having a mutation as well.

A new germline mutation that was not inherited from either parent is called a de novo mutation.

Apart from neo-Darwinian mechanisms such as mutation, translocation and duplication of genes, novelty may also arise by mutation-driven changes in gene regulation.

A single mutation can affect all downstream functional domains if a premature stop codon or framing error results; such a mutation can result in a completely unusable (or unsynthesizable) androgen receptor protein.

By impact on protein sequence *A frameshift mutation is a mutation caused by insertion or deletion of a number of nucleotides that is not evenly divisible by three from a DNA sequence.

Consequently, changes in the mutation rate or the selection pressure will result in a different Mutation–selection balance.

Females with recessive mutation crossed with wild-type males would yield the same phenotype as the wild-type, and any observable change to the phenotype would indicate that a mutation induced by the mutagen has occurred.

However, the concept of suppressing mutation raises the question: How can design evolution occur at the nanoscale without a process of random mutation and deterministic selection?

I-mutation in High German I-mutation is visible in Old High German (OHG), c. 800 AD, only on /a/, which was mutated to /e/.

Mutation mechanism and estimated mutation rates DNA strand slippage during replication of an STR locus.

Once DNA damage has given rise to a mutation, the mutation cannot be repaired.

Some people are resistant to certain strains of HIV. citation For example, people with the CCR5-Δ32 mutation are resistant to infection with R5 virus, as the mutation stops HIV from binding to this coreceptor, reducing its ability to infect target cells.

Special classes *Conditional mutation is a mutation that has wild-type (or less severe) phenotype under certain "permissive" environmental conditions and a mutant phenotype under certain "restrictive" conditions.

Such de novo mutations are the result of a germ cell mutation or germ cell mosaicism in the gonads of one of the parents, or a mutation in the fertilized egg itself.

The Huntington's disease mutation is genetically dominant and almost fully penetrant : mutation of either of a person's HTT alleles causes the disease.
