Isothermal detection of RNA with restriction endonucleases.
Herein, we demonstrate how to detect nucleic acids that do not contain restriction endonuclease recognition sites with restriction endonucleases. We show that the topology of DNA probes used in this detection strategy remarkably affects the efficiency of RNA/DNA detection.
متن کاملDigestion of DNA with restriction endonucleases.
Restriction endonucleases recognize short DNA sequences and cleave double-stranded DNA at specific sites within or adjacent to the recognition sequences. Restriction endonuclease cleavage of DNA into discrete fragments is one of the most basic procedures in molecular biology. The first method presented in this unit is the cleavage of a single DNA sample with a single restriction endonuclease. A...
متن کاملEstimating genetic variability with restriction endonucleases.
The estimation of the amount of sequence variation in samples of homologous DNA segments is considered. The data are assumed to have been obtained by restriction endonuclease digestion of the segments, from which the numbers and frequencies of the cleavage sites in the sample are determined. An estimator, p, of the proportion of sites that are polymorphic in the sample is derived without assumi...
متن کاملPCR–RFLP of isolated Salmonella from poultry with Sau3AI and HhaI restriction endonucleases in Arak
Salmonella enterica is considered as one of the major pathogens in public health, worldwide. Diseases caused by Salmonella enterica serovars are especially prevalent in developing countries. It is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. The aim of this study was to apply a PCR–RFLP method using Sau3AI and HhaI restriction endonucle...
متن کاملThe type IIB restriction endonucleases.
The endonucleases from the Type IIB restriction-modification systems differ from all other restriction enzymes. The Type IIB enzymes cleave both DNA strands at specified locations distant from their recognition sequences, like Type IIS nucleases, but they are unique in that they do so on both sides of the site, to liberate the site from the remainder of the DNA on a short duplex. The fact that ...
