TLDR
The generality of the arbitrarily primed PCR method is demonstrated by application to twenty four strains from five species of Staphylococcus, eleven strains of Streptococcus pyogenes and three varieties of Oryza sativa.Abstract:
Simple and reproducible fingerprints of complex genomes can be generated using single arbitrarily chosen primers and the polymerase chain reaction (PCR). No prior sequence information is required. The method, arbitrarily primed PCR (AP-PCR), involves two cycles of low stringency amplification followed by PCR at higher stringency. We show that strains can be distinguished by comparing polymorphisms in genomic fingerprints. The generality of the method is demonstrated by application to twenty four strains from five species of Staphylococcus, eleven strains of Streptococcus pyogenes and three varieties of Oryza sativa (rice).read more

TL;DR: The AFLP technique provides a novel and very powerful DNA fingerprinting technique for DNAs of any origin or complexity that allows the specific co-amplification of high numbers of restriction fragments.

TL;DR: The clinical picture was remarkably similar to that of the severe acute respiratory syndrome (SARS) outbreak in 2003 and reminds us that animal coronaviruses can cause severe disease in humans.

Ubiquitous somatic mutations in simple repeated sequences reveal a new mechanism for colonic carcinogenesis
TL;DR: It is shown that 12 per cent of colorectal carcinomas carry somatic deletions in poly(dA . dT) sequences and other simple repeats, and it is concluded that these mutations reflect a previously undescribed form of carcinogenesis in the colon mediated by a mutation in a DNA replication factor resulting in reduced fidelity for replication or repair (a 'mutator mutation').

TL;DR: A comparison of genetic similarity matrices revealed that, if the comparison involved both cultivated and wild soybean accessions, estimates based on RFLPs, RAPD, AFLPs and SSRs are highly correlated, indicating congruence between these assays.

Universal and rapid salt-extraction of high quality genomic DNA for PCR-based techniques
Salah M. Aljanabi,Iciar Martinez +1 more
TL;DR: The quantity and the quality of the DNA extracted by this method is high enough to perform hundreds of PCR-based reactions and also to be used in other DNA manipulation techniques such as restriction digestion, Southern blot and cloning.

DNA polymorphisms amplified by arbitrary primers are useful as genetic markers
TL;DR: A new DNA polymorphism assay based on the amplification of random DNA segments with single primers of arbitrary nucleotide sequence is described, suggesting that these polymorphisms be called RAPD markers, after Random Amplified Polymorphic DNA.

TL;DR: A method whereby a nucleic acid sequence can be exponentially amplified in vitro is described in the chapter, and the possibility of utilizing a heat-stable DNA polymerase is explored so as to avoid the need for addition of new enzyme after each cycle of thermal denaturation.

Fluorescent-oligonucleotide probing of whole cells for determinative, phylogenetic, and environmental studies in microbiology.
TL;DR: Fluorescent-dye-conjugated oligonucleotides were used to classify 14 Fibrobacter strains by fluorescence microscopy and the direct detection of F. intestinalis in mouse cecum samples demonstrated the application of this technique to the characterization of complex natural samples.

TL;DR: Quantitative microfluorimetry shows that the amount of an rRNA-specific probe that binds to Escherichia coli varies with the ribosome content and therefore reflects growth rate.
