Phylogenetic Study of Cirripedes and Selected Relatives (Thecostraca) Based on 18s Rdna Sequence Analysis
ABSTRACT Sequence data from PCR-amplified 18S rDNA were used to infer phylogenetic relationships among the thecostracan crustacean taxa Ascothoracida (Ulophysema oeresundense), AcrothoracicaExpand

Phylogeny of Selected Maxillopodan and Other Crustacean Taxa Based on 18S Ribosomal Nucleotide Sequences: A Preliminary Analysis
Relationships among the following taxa were examined based on 18S ribosomal RNA and DNA nucleotide sequences: Branchiopoda (Branchinecta packardi), Ostracoda (two podocopid species), BranchiuraExpand

In vitro mammalian mutagenesis as a model for genetic lesions in human cancer.
Recently in vitro assays of mutagenesis have been criticized as being poorly predictive of long-term in vivo rodent assays of carcinogenicity. Questions have also been raised concerning the relevanceExpand

Use of DNA purified in situ from cells embedded in agarose plugs for the molecular analysis of tk-/- mutants recovered in the L5178Y tk+/- 3.7.2C mutagen assay system.
Abstract We have reported that tk−/− mutants recovered in the mouse L5178Y tk+/− 3.7.2C mutagen assay have often lost the tk+ allele. Allele loss in the tk−/− mutants is documented on Southern blotsExpand
