释义 | mutational adjective biology specializeduk /mjuːˈteɪ.ʃən.əl/ us /mjuːˈteɪ.ʃən.əl/ relating to mutation(= change in genes or organisms): 突变的 mutational varianceMutational variance is high for mortality in infancy and early childhood.婴幼儿期死亡率的突变方差很大。 Tests evaluate the sunscreen's ability to protect against mutational effects. Mutational analysis in the patient showed a mutation of the gene that has not been identified before. In some cells a single mutational event can cause the tumour to develop. The surgeon did not have any knowledge of the mutational status of the gene. We performed mutational analysis of tumour specimens from several patients. Genetics accession number adenine anaphase autosomal autosomally genetic fingerprinting genetically genetically engineered geneticist genic genomic genomics monozygotic mutate non-familial non-genetic non-mutant nondominant nonhomologous sex-linked Related wordsmutation mutationally Examples of mutationalmutational Similar results are obtained for other values of rates of mutations and average mutational effects. Longevity in particular appears to be a small ' mutational target ', with large amounts of environmental variation. Deleterious mutations in a hybrid zone : can mutational load decrease the barrier to gene flow ? I neglect indels in this discussion, assuming that their mutational effects are usually so strongly deleterious that they are deterministically removed by purifying selection. Mutational analysis of acylphosphatase suggests the importance of topology and contact order in protein folding. Therefore, the inferred number of mutational events will be overestimated. The effect of linkage and population size on inbreeding depression due to mutational load. Therefore, any very small, and thus invisible, mutational effects potentially present should have been, on average, the same in both groups. We believe that the link between repeat generation and mutational hotspots exists because repetitive regions arise at mutational/ recombinational hotspots. Mutational variance is high for mortality early in life and essentially zero at the oldest age. On the whole, molecular data could be made consistent with any of the different mutational estimates discussed above. The results also have a bearing on considerations of mutational load. Assuming that we cannot change most mutational effects makes effective population size the second most important parameter. The sequence of nucleotides in that segment will be known, establishing the mutational diagnosis in the patient. Thus, our results could be relevant to mutational screens, toxicology screens, hormone treatments, and functional assessments of zebrafish retinal development and regeneration.
