(1) However, at the aprt locus the repair-deficient cells were much more highly mutable (9-15-fold) than the repair-proficient AT3-2 cells.
(2) It is postulated that the cartoon serves to stabilize the more mutable portrayals of psychiatrists in other media.
(3) However, this mutant was only slightly mutable by MNNG in comparison with the wild-type strain.
(4) Analysis of the bases neighboring the mutations appeared to be related to the mutability of the base pairs with the sequence of 5'-purine-G-G-3' being the most frequently mutated.
(5) Facts were mutable, and didn’t need to displace a good yarn.
(6) The uvrA- strain was more sensitive to induction of mutations by CMNU than the wild and polA- strains, but the recA- strain was hardly mutable by CMNU.
(7) Three UVS mutants were characterized by greatly increased mutability in all analysed loci; slight mutability was found in seven mutants.
(8) Multicopy plasmids carrying either the umuDC operon of Escherichia coli or its analog mucAB operon, were introduced into Ames Salmonella strains in order to analyze the influence of UmuDC and MucAB proteins on repair and mutability after UV irradiation.
(9) The P1CMrec plasmid was also involved in the creation of new mutant genes within the E. coli genome (not carrying recA), some mutabilities being very high upon extended incubation.
(10) The existence of gam3 and gam5 mutants indicates that at least two common steps control both nuclear DNA repair and the mutability of particular alleles of the mtDNA.
(11) Gene mutations in phage PZA were induced by hydroxylamine and their frequency was compared with the evolutionary mutability.
(12) The presence among wild mice of a haplotype (H-2u21) that appears to be very similar to a haplotype (H-2v) carried by an inbred strain (B10.SM) has some interesting implications for considerations of H-2 gene mutability.
(13) In excision deficient cells the effect of the plasmid on survival was less pronounced while cell mutability was increased.
(14) Similar type of different mutability was found in mutagen-sensitive strain mus-201G1 and in the control 3-4 strain having the same genetical background as mus mutation.
(15) In non-UV-mutable umu and lexA strains, UV mutagenesis can be demonstrated if delayed photoreversal is given.
(16) The chronology of genetic events leading to the discovery of mu implicates, but does not prove, the insertion of a "foreign" DNA segment as the basis of mutability.
(17) High mutability, disturbance of the development of the life cycle and genetic instability are traits which resemble hybrid dysgenesis in Drosophila and meiotic dysgenesis in Phycomyces.
(18) No marked effect of the mutation on UV-mutability at lower doses was apparent.
(19) Previous studies have shown the non-mutability of Haemophilus influenzae either by UV irradiation of the cells or by irradiating the transforming DNA and transformation of competent cells.
(20) With respect to mutability the BC1 descendants of both types could be divided into two classes.
