Macronuclear persistence of sequences normally eliminated during development in Tetrahymena thermophila
(Wiley Subscription Services, Inc., A Wiley Company, 1985)
During conjugation in the ciliated protozoan, Tetrahymena thermophila , a somatic MAC-ronucleus develops from the germinal MICronucleus. Ten to 20 percent of the MIC genome is eliminated during this process. Three repetitive ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
Data subset selection by Boolean calculation
(Elsevier, 1984-11)
In this journal in 1969 the authors described an unconventional method, based on concepts from systematic biology, for storing and retrieving data, whose salient features are: (1) data are stored in such a manner that the ...
An idealized concept of the true cladistic character
(Elsevier, 1975-04)
Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which such estimates are founded. Some ...
Chemical permeabilization and in situ removal of daidzein from biologically viable soybean (Glycine max) seeds
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-09)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 ± 0.0045 mg/g seed dry wt) obtained by physical grinding. With ...
The alkanes of the ant, Atta colombica
(Elsevier, 1970)
Two homologous series of trimethylalkanes, the 3,7,11-trimethylalkanes (C34H7), C36H74 and C38H78) and the 4,8,12-trimethylalkanes (C35H72, C37H76 and C39H80) are the major constituents of the cuticular alkanes of the ant, ...
