Intersyngenic variations in the esterases of bacterized Paramecium aurelia
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-04)
The esterase isozymes were surveyed in bacterized stocks representative of all 14 syngens of Paramecium aurelia by starch gel electrophoresis. The properties of substrate specificity and independent variation of particular ...
Genome amplification and gene expression in the ciliate macronucleus
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1972-06)
The focus of this review is on the micronucleus and macronucleus in the ciliated protozoa and the organization and function of the DNA molecules within them. We present (1) some of the structural and functional differences ...
Intersyngenic variations in the esterases of axenic stocks of Paramecium aurelia
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-04)
The esterase isozymes were surveyed in axenic stocks of syngens 1, 2, 4, 5, 6, and 8 of Paramecium aurelia by starch gel electrophoresis. In paramecia there appear to be four types of esterases which are clearer in axenic ...
Intersyngenic variations in the esterases and acid phosphatases of Tetrahymena pyriformis
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-04)
The esterase and acid phosphatase isozymes were surveyed in strains of syngens 2–12 under conditions found to be optimal for syngen 1. Both intersyngenic and intrasyngenic variations were found. Comparisons of the esterases ...
Nucleotide sequence divergence among DNA fractions of different syngens of Tetrahymena pyriformis
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-09)
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 repeated sequences ...
