Sentence examples for mutations are occurring from inspiring English sources

In case 3, the cooperative lineage expansion case with late mutator mutation, the situation is analogous to case 2 except that the mutator mutation occurs after the onset of lineage expansion, during the period when additional oncogenic mutations are occurring towards reaching a fully malignant phenotype.

Mutations are occurring in COL7A1, the gene encoding for collagen, type VII, alpha 1 [ 8].

In nature, de novo mutations are occurring randomly and are constantly subjected to natural selection.

The intuitive picture is that selection would drive mutation rate toward a maximum value when beneficial mutations are occurring [ 19].

If mutations are occurring at random throughout the genome, then over the relatively short duration of this MA experiment (27 generations), it is reasonable to assume that mutations accumulating within a given MA line occurred in different genes.

This suggests that in p-endosymbionts the mutation rate at this locus is not constant, but that mutations are occurring much more frequently in young p-endosymbionts and slowing as the symbioisis ages.

As the allele frequency distribution from CNCs was shifted towards rare alleles relative to non-conserved sequences, the authors concluded that selection against deleterious mutations was occurring in CNCs, and thus such sequences were likely to be functional and not in fact mutationally cold.

No mutations were occurred in other 6 loci.

Among the most frequent mutations are those occurring in genes that are activated by interferon and in genes that play a role in regulating immune response.

Today, these mutations are rare, occurring in only about one of every 25,000 human births.
