  2. 16. Optical Mapping of Bacterial Plasmids

    Author : Vilhelm Müller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; competitive binding; optical mapping; fluorescence microscopy; DNA; plasmids; CRISPR Cas9; antibiotic resistance; nanofluidics; single-molecule;

    Abstract : Bacteria that have acquired resistance to antibiotics represent one of the largest threats to human health and modern health care. The genes encoding resistance are frequently spread via the transfer of plasmids, which are circular double stranded DNA molecules separate from the chromosomal DNA of the bacteria. READ MORE
