African bees in the Americas: Insights from biogeography and genetics
(Elsevier, 1991-01)
The spread of African honey bees in South and Central America is one of the most remarkable and certainly among the most highly publicized instances of biological invasion. Their aggressive nest defense has led to numerous ...
Embryonic regulation of histone ubiquitination the sea urchin
(Wiley Subscription Services, Inc., A Wiley Company, 1995)
We have used quantitative 2-D protein electrophoresis and immunoprecipitation to study the patterns of histone ubiquitination at 10 h and 36 h of embryonic development in Strongylocentrotus purpuratus. Variants csH2A, ΑH2A, ...
Interaction between bacteriophage [lambda] and its Escherichia coli host
(Elsevier, 1992)
Bacteriophage [lambda] relies to a large extent on processes requiring interactions between viral- and host-encoded proteins for its lytic growth, establishment of lysogeny, and release from the prophage state. Both ...
Genetic structure of five susceptibility gene regions for coronary artery disease: disequilibria within and among regions
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
We analyzed two-locus disequilibria for 16 polymorphic loci of seven susceptibility genes for coronary artery disease located in five chromosomal regions distributed across four chromosomes. Included were the genes coding ...
Intragenic complementation between Escherichia coli trp repressors with different defects in the tryptophan-binding pocket
(Elsevier, 1992-08-01)
Site-directed mutagenesis of the trpR gene (encoding the trp repressor, TrpR) was used to replace Gly85 with tryptophan (Trp or W), in order to place Trp near its normal location in the -tryptophan(-W)-binding pocket. The ...
Detection of oxidative mutagens in an urban air-particulate extract: a preliminary study
(Elsevier, 1992-12)
The Ames assays strains TA98 and TA100 have been useful in characterizing complex mixtures from organic solvent extracts of particles from diesel-powered vehicles, ambient air, and other sources. In this paper we report ...
An Integrated Physical Map of 210 Markers Assigned to the Short Arm of Human Chromosome 11
(Elsevier, 1994-06)
Using a panel of patient cell lines with chromosomal breakpoints, we constructed a physical map for the short arm of human chromosome 11. We focused on 11p15, a chromosome band harboring at least 25 known genes and associated ...
Rapid generation of region-specific genomic clones by chromosome microdissection: Isolation of DNA from a region frequently deleted in malignant melanoma
(Elsevier, 1992-11)
Malignant melanoma is frequently characterized by the deletion of the long arm of chromosome 6 (usually encompassing 6q16-q21). In an effort to saturate this region with DNA markers, microdissection and molecular cloning ...
