Sentence examples for mutations the occurrence from inspiring English sources

For example, questions about altruistic behaviors, the importance of neutral mutations, the occurrence of directed or adaptive mutations, sympatric speciation, rates of speciation, and directionality of change have altered the thinking of many people over past decades.

Consensus is growing that biological parameters such as the frequency of resistance mutations, the occurrence of low- or no-cost drug-resistance mutations, epistasis between resistance mutations, as well as host genetics should be considered when deciding on future treatment protocols [ 88].

Although both the genomic distribution of mutations and the occurrence of various convergent mutations at specific genomic sites indicated that either mutation hotspots or selection for adaptive mutations might elevate observed mutation rates in MSV, we found no association between recombination and mutation rates.

Thus, the broad phenotypic differences between class 1 and class 2 disease stem from genetic differences while the differences between subclasses of class 1 disease might be related to the presence of additional mutations or the occurrence of EPAS1 mutations during embryonic development or later in life.

The presence of accompanying deleterious mutations, the high degree of recurrence of the polymorphic mutations, and the occurrence of epistatic interactions generate a highly complex interference dynamics.

The presence of additional mutations accompanying the polymorphic ones, the high frequency of recurrent mutations, and the occurrence of epistatic interactions contribute to generate a highly complex dynamics that would likely require improved theoretical models to be successfully described.

Taken together, the role of EGFR gene mutations in the occurrence of distant metastases remains controversial.

Indeed, recent case control studies found an association between FLG mutations and the occurrence of occupational HE 31– 31.

Taking into account the sum total of information now available about the effects of bldA mutations, and the occurrence and nature of TTA-containing genes in streptomycetes, we suggest the following bldA-centred model of Streptomyces physiology.

The presence of resistance mutations and the occurrence of heteroresistance could not only guide the need for simultaneously initiating first- and second-line DST, but also significantly reduce the delay in administering an appropriate regimen to an MDR (or extensively drug resistant) TB case.

The probability of a He atom escaping into vacuum from a trap mutation depends on the type of the trap mutation, and the occurrence probabilities of the different types of trap mutations are dependent on the temperature.
