Horizontal compensatory eye movements in goldfish ( Carassius auratus )
(Springer-Verlag, 1974-03)
1. Goldfish were deprived of visual input and/or normally functional horizontal semicircular canals.
Hyperproduction of some glycosidases in Neurospora crassa
(Springer-Verlag, 1974-01)
Results of a cross between a hyperderepressed strain (89601 a) and a normal strain (74A) of Neurospora crassa suggest that there is a single gene difference in this trait. The evidence is clearest with amylase although a ...
Histologische, funktionelle und spezifische Regeneration nach Durchtrennung der Fila olfactoria beim Goldfisch ( Carassius auratus )
(Springer-Verlag, 1970-03)
1. Alter dissection of the olfactory libres (fila olfactoria, Fig. 1) in the goldfisch, histological (Fig. 5) as well as functional regeneration takes place. When regeneration of the olfactory fibres was complete, no ...
Age-dependent allozymic variation in a natural population of lizards
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-03)
An analysis of allozymic variation at 17 loci in a population of the sagebrush lizard ( Sceloporus graciosus ) in southern Utah yielded an estimate of genic heterozygosity of 0.028. Seven of the loci were variable, but ...
RNA dependent DNA synthesis in cell free preparations of human leukemia cells
(Elsevier, 1971-02-19)
A cell free preparation of human leukemic cells, grown in tissue culture, incorporated H3-thymidine phosphate into an acid insoluble product which was rendered acid soluble by the action of DNAase but not KOH or RNAase. ...
A general analysis of resource allocation by competing individuals
(Elsevier, 1975-08)
The analysis presented in this paper is constructed to determine the pattern of resource allocations among competing individuals of the same and/or different species in some defined habitat. Competing individuals have at ...
Cytochrome P-450 purified to apparent homogeneity from phenobarbital-induced rabbit liver microsomes: Catalytic activity and other properties
(Elsevier, 1974-09-23)
Cytochrome P-450 was purified to a content of over 17 nmoles per mg of protein from liver microsomes of phenobarbital-treated rabbits by fractionation with polyethylene glycol 6000, DEAE-cellulose column chromatography, ...
Discrimination between groups of chromosomes and individual chromosomes in the normal human karyotype
(Springer-Verlag, 1973-09)
The karyotypes of 200 normal individuals are examined in a study designed to investigate the extent to which the cytologist's classification of chromosomes into the A–G autosomal groups and identification of individual ...
Evolutionary and phylogenetic relationships of rubredoxin-containing microbes
(Elsevier, 1971-02-19)
The primary structure of the rubredoxin, except for the placement of several residues, is presented. There is evidence for gene duplication in the rubredoxin. When the primary structures of this rubredoxin and the ...
Intermediates in flavoprotein catalyzed hydroxylations
(Elsevier, 1974-04-23)
The reaction of molecular oxygen with the complex of reduced p-hydroxybenzoate hydroxylase and 2,4-dihydroxybenzoate has been followed by rapid reaction techniques. During the reaction, which produces stoichiometric amounts ...
