| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies.

| blue-green bacteria | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nitrogen fixation occur at regular intervals. According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |
