Type II restriction endonucleases — a historical perspective and more
This article continues the series of Surveys and Summaries on restriction endonucleases (REases) begun this year in Nucleic Acids Research. Here we discuss 'Type II' REases, the kind used for DNA analysis and cloning. We focus on their biochemistry: what they are, what they do, and how they do it. Type II REases are produced by prokaryotes to combat bacteriophages. With extreme accuracy, each r...
متن کاملType III restriction-modification enzymes: a historical perspective
Restriction endonucleases interact with DNA at specific sites leading to cleavage of DNA. Bacterial DNA is protected from restriction endonuclease cleavage by modifying the DNA using a DNA methyltransferase. Based on their molecular structure, sequence recognition, cleavage position and cofactor requirements, restriction-modification (R-M) systems are classified into four groups. Type III R-M e...

متن کاملTechnology and Urban Form: A Philosophical and Historical Perspective
Urban form has undergone tremendous changes throughout history. These changes have stemmed from various causes. Technology has been one of the most influential forces in changing the face of cities, leaving different marks on the city form. In fact, technology has gained an increasingly more important and integrative role in bringing changes to the urban form. In addition, recent plethora of de...
متن کاملHistorical Perspective
An article by Dr. H. L. Feffer, in Medical World News in September, 1978 entitled Arachnoiditis Risk After Myelography, suggested that the at least a quarter of patients undergoing a myelogram (400,000 then being performed every year in the US) develop iophendylate arachnoiditis and furthermore, that those undergoing two or more myelogram studies have a 50% chance of developing iatrogenic arach...
