    A phylogenetic comparison of mutation spectra

    Spectra of induced mutations resulting in obligate organoauxotrophy are compared at different phylogenetic levels from bacteria to higher plants. It appears that the spectra of mutants concerned with basic cel...

    Thiamine mutants of the crucifer, Arabidopsis

    In higher plants the only obligate organoauxotrophic mutants available are concerned with the synthesis of thiamine, vitamin B1. In Arabidopsis 65 mutants, representing four loci controlling four different steps ...

    A study of genetic polymorphisms of milk β-lactoglobulin, αS1-casein, β-casein, and κ-casein in five dairy breeds

    Gene frequencies of the milk β-lactoglobulin, αS1-casein, β-casein, and κ-casein loci have been estimated from 1663 cows of five dairy breeds. Departure from Hardy-Weinberg equilibrium was found only in the κ-cas...

    Nucleotide sequence divergence among DNA fractions of different syngens of Tetrahymena pyriformis

    The magnitude of the differences in base sequence of DNA fractions derived from different syngens of the ciliated protozoan Tetrahymena pyriformis was investigated. Each DNA was fractionated into unique and repea...

    A virus-specified mechanism for the prevention of multiple infection—T7- and T3-mutual and superinfection exclusion

    Co-and superinfection of cells with T3/T7 result in exclusion (mutual or superinfection exclusion). The exclusion mechanism is also directed against homologous (or identical) virus. Exclusion is established af...

    E. coli membranes become permeable to ions following T7-virus-infection

    Infection of E. coli with the viruses T7 or T3 leads to a dramatic efflux of potassium ions. This ion efflux is caused by the virus particle since no concomitant protein synthesis is required. T7 mutants carrying...

    Correlation between structural variation and activity of murine kidney β-galactosidase: Implications for genetic control

    Two closely linked regulatory genes have been reported to control activity levels of β-galactosidases in murine tissues. The specific effects of these genes on murine glycolipid metabolism have not been elucid...

    Early T7 gene expression

    The mode of transcription of early T7 genes starting from one promotor region and generating a unique polycistronic RNA species suggests the appearance of equimolar amounts of the monocistronic species after R...

    The half-life of mRNA in Saccharomyces cerevisiae

    The decay kinetics of mRNA was studied in a yeast temperature-sensitive mutant, ts136, which is defective in cytoplasmic RNA production at 37° C. The disappearance of the synthetic capacity of mRNA was determined...

    Radiation sensitivity of messenger RNA

    Messenger RNA function is inactivated by irradiation with ultraviolet light. A unit length mRNA (in bases) is 2–3 times more sensitive than a unit length of DNA (in base pairs) with respect to the inactivation...

    Structural relatedness of mouse lactate dehydrogenase isozymes, A4 (muscle), B4 (heart), and C4 (testis)

    Three homotetrameric lactate dehydrogenase isozymes, LDH-M(A4), LDH-H(B4), and LDH-X(C4), from DBA/2J mice have been purified by affinity chromatography. The amino acid compositions of the subunits A, B, and C, b...

    Nitrogen regulation of uricase synthesis in Neurospora crassa

    Neurospora crassa can utilize various purine bases as a nitrogen source. Synthesis of the purine catabolic enzymes such as uricase requires induction by the intermediate uric acid and is also subject to nitrogen...

    Evidence for the transcription of physiologically inactive rat-liver nucleolar chromatin byEscherichia coli RNA polymerase

    Rat-liver nucleoli (10-15 pg DNA) were digested with either 0.6 or 3 units of DNase I for various times (up to 1 h). RNA synthesis was then measured in the absence or presence ol 3 units ofEscherichia coli RNA po...

    Polymorphism of human liver alcohol dehydrogenase: Identification of ADH2 2-1 and ADH2 2-2 phenotypes in the Japanese by isoelectric focusing

    Liver homogenate-supernatants from most Japanese exhibit an “atypical” pH optimum for ethanol oxidation at pH 8.8 instead of 10.5, the “typical” pH-activity optimum. It has been proposed that atypical livers cont...

    Purification and characterization of mouse alcohol dehydrogenase from two inbred strains that differ in total liver enzyme activity

    Alcohol dehydrogenase activity in mouse liver homogenate-supernatants is 1.7 times greater in the C57BL/10 strain than in the BALB/c strain, regardless of whether activity is expressed in units per gram liver,...
