Inhibitors of preferentially stimulated deoxyribonucleic acid synthesis in pneumococci.
During experiments with Haemophilus gallinarum, mycoplasma of similar identity, were isolated from the infraorbital sinuses of chickens with coryza. These organisms were unrelated, serologically and by standard biochemical tests, to any other mycoplasma of avian origin. Furthermore, the organisms grew at room temperature in the absence of serum proteins, and were not pathogenic to either chicke...
متن کاملEnzymatic Synthesis of Deoxyribonucleic Acid. Deoxyribonucleic Acid By
MISSOURI The enzymatic synthesis of DNA1 in sufficient excess over the DNA used to prime the reaction21 a has enabled us to examine the chemical composition of the synthetic product. As has already been demonstrated, this DNA consists of deoxy-nucleotides Linked by typical 3'-5' phosphodiester bonds, and all four of the deoxy
متن کاملCapacity of virulent Treponema pallidum (Nichols) for deoxyribonucleic acid synthesis.
Treponema pallidum (Nichols) was extracted from infected rabbit tissue, and cell lysates were prepared for monitoring thymidine kinase and deoxyribonucleic acid polymerase activities. No thymidine kinase could be demonstrated in preparations of T. pallidum or the cultivable T. phagedenis biotype Reiter. Significant levels of deoxyribonucleic acid polymerase were detected in both treponemal samp...
متن کاملDeoxyribonucleic Acid Synthesis
Exposure of Escherichia coli cells to myxin results in the almost complete in'hibition of new deoxyribonucleic acid (DNA) synthesis, extensive degradation of pre-existing intracellular DNA, and a rapid loss of viability in these cells (9). After exposure to myxin for 30 min (<1% survivors and >25% degradation of DNA), infection of these cells by T4 bacteriophage results in the renewal of DNA sy...
متن کاملRegulation of Deoxyribonucleic Acid Synthesis
These enzymes (Grav, 1967) are responsible for the synthesis of the monomeric precursors of DNA, namely dATP, dCTP, dGTP and dTTP. Fluctuations in the activities of some of the enzymes and in the intracellular deoxyribonucleotide pools are known to occur throughout the cell cycle (Grav, 1967; Nordenskjold et al., 1970; Adams et al., 1971 ; Skoog & Nordenskjold, 1971). Moreover, there is inducti...
