Bacterial DNA in Clarkia fossils
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1991For the growing number of investigators who study ancient DNA, the most stimulating paper published during 1990 reported the determination of a chloroplast DNA sequence from a plant compression fossil found in a Miocene deposit at Clarkia, Idaho (Golenberg et al. 1990). During August 1990, S.P.

DNA uptake during bacterial transformation
Nature Reviews Microbiology, 2004Naturally competent bacteria are able to take up exogenous DNA and undergo genetic transformation. The transport of DNA from the extracellular milieu into the cytoplasm is a complex process, and requires proteins that are related to those involved in the assembly of type IV pili and type II secretion systems, as well as a DNA translocase complex at the

Untangling bacterial DNA topoisomerases functions
Biochemical Society TransactionsTopoisomerases are the main enzymes capable of resolving the topological constraints imposed by DNA transactions such as transcription or replication. All bacteria possess topoisomerases of different types. Although bacteria with circular replicons should encounter similar DNA topology issues, the distribution of topoisomerases varies from one ...

Preparation of Bacterial Plasmid DNA
Current Protocols in Neuroscience, 1998AbstractThe protocols in this unit describe methods for preparing bacterial plasmid DNA free from chromosomal DNA. The first is an alkaline lysis miniprep suitable for screening a moderate number of bacterial colonies by restriction endonuclease cleavage and agarose gel electrophoresis.

Bacterial Dna in Mixed Cholesterol Gallstones
American Journal of Gastroenterology, 1999Numerous investigators have proposed a role for bacteria in biliary lithogenesis. We hypothesized that bacterial DNA is present in gallstones, and that categorical differences exist between gallstone type and the frequency of bacterial sequences.Polymerase chain reaction (PCR) was used to amplify bacterial 16S rRNA and uidA (encoding Escherichia coli ...

Bacterial DNA strand compositional asymmetry
Trends in Microbiology, 1999Genes that deviate strongly in codon usage from the average gene but are relatively similar in codon usage to ribosomal protein (RP) genes are viewed as highly expressed22xKarlin, S., Campbell, A.M., and Mrazek, J.

Bacterial DNA Methylation and Methylomes
2016Formation of C5-methylcytosine, N4-methylcytosine, and N6-methyladenine in bacterial genomes is postreplicative and involves transfer of a methyl group from S-adenosyl-methionine to a base embedded in a specific DNA sequence context. Most bacterial DNA methyltransferases belong to restriction-modification systems; in addition, "solitary" or "orphan ...

DNA transfer and DNA synthesis during bacterial conjugation
Zeitschrift f�r Vererbungslehre, 1966Mutant strains ofEscherichia coli, which were thermosensitive with respect to DNA replication, were used for conjugation experiments at 37°C and 42°C. Inhibition of DNA synthesis in the donor strain has no influence on the yield of recombinats. Inhibition of DNA synthesis in the recipient strain is accompanied by a complete loss of recombinant ...
