In the early 1960s, extraordinary mutations were discovered in the drosophila fly: modifying particular genes termed homeotic genes produced mutants that had legs where their antennae should be (Lewis et al., 1980).
For instance, with the new data from the present study, the extraordinary mtDNA mutation pattern observed in one of the two CD34+ cells in [24] could be resolved: the contaminant DNA present in the bone marrow donor (BM donor 2, U6a1) turned out to be the haplogroup D4c1a type matching the mtDNA of member 2, who handled the sample and performed the analysis at the time [24].
There is extraordinary variation in the frequency and spectrum of somatic mutations affecting different cancers, shedding light on the underlying mutational processes and disease etiology of these tumors (Wheeler and Whang, 2013).
Since it was difficult to find DNA imports in the strain 26695mutY due to the high background of spontaneous mutations and extraordinary low recombination levels in 26695ruvB, it was necessary to screen the Rif resistant clones after transformation by an import specific PCR using the primers HPrpoB-IscrX and HPrpoB-4.
We note that there are plausible reconstructions other than those presented in Figure 3A, but all would result in the same extraordinary number of convergent or reversion mutations.
Aberrant alternative splicing caused by intronic or exonic point mutations in patients leads to an extraordinary increase in P3A and a concomitant decrease in P3A.
It is now possible to analyze a woman's blood for the presence of a BRCA mutation, giving her the option of taking extraordinary preventive measures, including undergoing a double prophylactic mastectomy.
Recent work has demonstrated an extraordinary degree of selfing combined with a high deleterious mutation rate in contemporary populations.
The optimized 10E8 antibody, with mutations to phenylalanine and arginine, retained the extraordinary breadth of 10E8 but with ∼10-fold increased potency.
It is the combination of mutation and the selection filter that produces the extraordinary instances of adaptation we can document in nature.
