The substitution of a purine for a pyrimidine, or a pyrimidine for a purine.
Industry:Biotechnology
The sub-unit of prokaryotic RNA polymerases that is responsible for the initiation of transcription at specific initiation sequences.
Industry:Biotechnology
The sum total of events that contribute to the progressive elaboration of an organism. The two major aspects of development are growth and differentiation.
Industry:Biotechnology
The suppression of immune response. Immunosuppression is necessary following organ transplants in order to prevent the host rejecting the grafted organ.
Industry:Biotechnology
The synthesis of a whole set of DNA repair, recombination and replication proteins in bacteria containing severely damaged DNA (e.g., following exposure to UV light).
Industry:Biotechnology
The synthesis of antibodies by B cells in response to an encounter of the cells of the immune system with a foreign immunogen.
Industry:Biotechnology
The synthesis of antigen-specific T cell receptors and the development of killer T cells in response to an encounter of immune system cells with a foreign immunogen.
Industry:Biotechnology
The synthesis of DNA on a template of RNA, accomplished by reverse transcriptase.
Industry:Biotechnology
The synthesis of duplex (double-stranded) DNA by copying from a single-stranded template.
Industry:Biotechnology
The synthesis of proteins in the test-tube from purified mRNA molecules using cell extracts containing ribosomal sub-units, the necessary protein factors, tRNA molecules and aminoacyl tRNA synthetases, ATP, GTP, amino acids and an enzyme system for re-generating the nucleoside triphosphates. Prokaryotic translation systems are usually prepared from <i>E. coli</i> or the thermophilic bacterium, <i>Bacillus stearothermophilus.</i> Eukaryotic systems usually employ rabbit reticulocyte lysates or wheat germ.
