During the normal growth of an ascites tumor (Landschutz) the intracellular concentration of the ribonucleic acids (RNA) decreases by about 50%. At the same time, the amounts of protein, free… (More)
Abstract The study of the in vitro action of ribonuclease, on a series of suspensions of ascites cells in different physiological conditions, shows that the activity of the cellular membrane and the… (More)
In Chlamydomonas reinhardi, the activity of the neutral phosphatase considerably increases when the cells are grown in the absence of inorganic phosphate (Pi). A comparative immunological study of… (More)
There is now good evidence that higher plant cells can take up exogenous foreign DNA (1–13).
Publisher Summary The chapter discusses the uptake of DNA, by living cells. The chapter describes the actual evidence concerning DNA uptake, by tissues and organs. The data obtained up to now… (More)
Thiamineless mutants of Arabidopsis were corrected by treating the seeds with DNA preparations from various bacteria. Possible mechanisms for this are discussed.
Heteropycnic labelled bacterial DNA's (DNA's of different density) are taken up by barley root cells and less rapidly by the shoot. Some of these molecules combine with the endogenous DNA (d = 1.702… (More)
Cesium chloride-ethidium bromide density gradient centrifugation and sedimentation velocity studies show the presence of plasmid DNA in several strains of Rhizobium.
Uptake of homologous and heterologous radioactively labelled DNA was studied in ten Streptomyces species. Among these, S. kasugaensis and S. virginiae were shown to take up 0.5-2.0% of the supplied… (More)
