The DNAs of the two fastidious adenovirus species 40 and 41 (Ad40 and Ad41) have been
studied by restriction endonuclease cleavage, CsCl density gradient centrifugation, and liquid…

To determine whether differences in structure and organization of the transforming regions
of Ad40 and Ad41 could explain the fastidious growth of these viruses, we have sequenced …

An electron microscopic study of isolated yeast nuclei demonstrated that the isolation procedure
yields pure preparations of morphologically intact nuclei. A combined biochemical and …

Nononcogenic adenovirus 2 (Ad2) and adenovirus 5 (Ad5) are able to transform rodent cells
in vitro (Freeman et al. 1967; Williams 1973). Graham et al.(1975) showed that only the left …

In order to establish whether the poor growth of the two fastidious adenoviruses types 40 and
41 (Ad40 and Ad41) in HeLa cells is due to a reduced trans-activation by the early region …

In vivo methylated precursors of ribosomal RNA in yeast have been characterized on
acrylamide gels. The initial ribosomal precursor in the yeast nucleus is a 37S RNA component, …

A fraction rich in dense crescent material, as judged by electron microscopy, has been
isolated from yeast nuclei. Double-labelling experiments with 14 C-uracil and 3 H-Me-methionine …

A deoxyribonucleoprotein complex was isolated from Saccharomyces cerevisiae. It is
composed of 36% DNA, 4% RNA and 60% protein. About 70% of the protein is acid-extractable. …

To study the transforming capacity of the two fastidious adenoviruses 40 and 41 (Ad40 and
Ad41), we have cloned the left terminal regions of their genomes. Transfection with plasmids …

The localization of adenovirus type 5 DNA replication has been investigated by both fractionation
of isolated nuclei and electron-microscope autoradiography. Nuclear fractionation by …
