Replicating DNA molecules of the colicin E1 plasmid isolated from minicells are cleaved at a single site by R1 restriction endonuclease (EcoR1). Electron microscopic measurements of the replicating ...
Sizeable differences in gene expression means and ratios—based solely upon where genes are located on a plasmid (gene syntax)—have been discovered by researchers at Dartmouth College. This new ...
A collaboration of researchers from Harvard Medical School and the University of Virginia, led by Dr. Anindya Dutta, has created an artificial mammalian origin of replication that will facilitate the ...
