A clear spot on an otherwise opaque culture plate of bacteria or cultured bacteria cells, showing where cells have been lysed by viral infection.
Industry:Biotechnology
A cloning vector carrying a DNA sequence capable of participating in a crossing-over event at a specified chromosomal location in the host cell.
Industry:Biotechnology
A cloning vector for the yeast <i>Saccaromyces cerevisiae</i> that uses 2mm plasmid as origin of replication and is maintained as an extrachromosomal nuclear DNA molecule.
Industry:Biotechnology
A cloning vector that allows the foreign gene or DNA sequence to be transcribed <i>in vitro.</i>
Industry:Biotechnology
A cloning vector that has been constructed in such a way that, after insertion of a DNA molecule, its coding sequence is properly transcribed and the RNA is translated. The cloned gene is put under the control of a promoter sequence for the initiation of transcription, and often also has a transcription termination sequence at its end. Such promoters are termed <i>high level</i>; examples include P1 (the leftward promoter of phage l) and the promoter of the yeast PGK (phosphoglycerate kinase) gene.
Industry:Biotechnology
A coarse filter used to screen out large particles before air is forced through a much finer filter.
Industry:Biotechnology
A collection of cDNA clones that were generated <i>in vitro</i> from the mRNA sequences isolated from an organism or a specific tissue or cell type or population of an organism.
Industry:Biotechnology
A collection of clones containing the genomic DNA sequences of an organism. Typically, these molecules are propagated in bacteria or phage. The library is an important tool used in the process of isolating genes.

Industry:Biotechnology
A commensal bacterium inhabiting the colon of many species. <i>E. coli</i> is widely used in biology, both as a simple model of cell biochemical function and as a host for molecular cloning experiments. In environmental studies, it is a key indicator of water pollution due to human sewage effluent.
