We have synthesized a 582,970-base pair Mycoplasma genitalium genome. This synthetic genome, named M. genitalium JCVI-1.0, contains all the genes of wild-type M. genitalium G37 except MG408, which was disrupted by an antibiotic marker to block pathogenicity and to allow for selection. To identify the genome as synthetic, we inserted "watermarks" at intergenic sites known to tolerate transposon insertions. Overlapping "cassettes" of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate (...) assemblies of approximately 24 kb, 72 kb ("1/8 genome"), and 144 kb ("1/4 genome"), which were all cloned as bacterial artificial chromosomes in Escherichia coli. Most of these intermediate clones were sequenced, and clones of all four 1/4 genomes with the correct sequence were identified. The complete synthetic genome was assembled by transformation-associated recombination cloning in the yeast Saccharomyces cerevisiae, then isolated and sequenced. A clone with the correct sequence was identified. The methods described here will be generally useful for constructing large DNA molecules from chemically synthesized pieces and also from combinations of natural and synthetic DNA segments. 10.1126/science.1151721.

Much has been written about prisoner research and the controversies surrounding prisoners as human subjects. The Institute of Medicine recently released a report addressing some of these issues. This report, which generated further controversy, needs to be fully discussed in the literature and certain aspects are examined in this work. Further, in the body of literature there has been little acknowledgement of the concept of the right of prisoners to be involved in research. This needs to be pursued from an (...) ethical perspective and eventually a legal one. This paper explores that concept and documents some facilities in which a prisoner's right to research has occurred. (shrink)

This 1979 text addresses the ways in which the dominant theories in large areas of Western social science have been subject to strong criticisms, particularly ...

After a definition of ?common sense? it is argued that sociology and common sense both do and ought to interact with one another. Four positions on the sociology?common sense relation in the light of the interaction thesis are then critically discussed: sociology must break with common sense; sociology must be based on common sense; sociology and common sense are incomparable; and sociology and common sense are identical. The first two of these positions are further sub?divided in terms of whether the (...) arguments in their favour are or are not independent of one's conceptions of sociology and common sense. Each of these positions is illustrated by means of a case study of one author. The final section involves a consideration of ethnomethodology on the basis of the above typology: it is argued that ethnomethodology cannot find a site on the sociology?common sense question which is compatible with its basic commitments.
