Recombinant in Biological Definition

Polymerase chain reaction

... in biological washing powders. The incorporation of an affinity tag on a recombinant protein will generate a fusion protein which can be more easily ... together on the same chromosome [Linkage Disequilibrium]) or detection of recombinant chromosomes and the study of meiotic recombination. Comparison of ...

Affinity chromatography

... free extracts and antibody purification from blood serum . Possibly the most common use of affinity chromatography is for the purification of recombinant proteins. Essentially proteins are tagged with a known affinity ligand in order to aid their purification. That is to say that the molecule has an ...

Bacterium

... development of a transverse cell wall. However, independent of sexual reproduction, genetic variations can occur within individual cells through recombinant events such as mutation (random genetic change within a cell's own genetic code). Similar to more complex organisms, bacteria also have mechanisms ...

Biotechnology

... word biotechnology 1975 Method for producing monoclonal antibody developed by Kohler and Milstein 1980 Modern biotech is characterized by recombinant DNA technology . The prokaryote model, E. coli , is used to produce insulin and other medicine, in human form. (About 5% of diabetics are ...

Chromatography

... covalent binding between histidine or other unique amino acids (either naturally present on the surface of the protein or grafted with recombinant DNA techniques ) and various immobilized metal ions, such as copper, nickel, zinc, or iron. Salt concentration is increased to produce later ...

Chromosomal crossover

... of crossing over was first demonstrated by Harriet Creighton and Barbara McClintock in 1931 . See also Genetic recombination recombinant frequency ...

Genetic recombination

... the mobile element and the target DNA, allowing the mobile DNA to enter the sequence. The nicks are then removed by ligases . See also recombinant frequency References Alberts, B. et al., Molecular Biology of the Cell , 3rd Edition. Garland Publishing, 1994. ...

Hepatitis B

... accidentally stuck by a needle used in a hepatitis B carrier would qualify. Treatment must be soon after exposure, however. Prevention A recombinant vaccine is available to prevent hepatitis B. Many countries now routinely vaccinate infants against hepatitis B. In many areas, vaccination ...

James D. Watson

... Molecular Biology of the Cell although here his role was more of coordinator of an outstanding group of scientist-writers. His third textbook was recombinant DNA which used the ways in which genetic engineering has brought us so much new information about how organisms function. All the textbooks are ...

Thomas Hunt Morgan

... findings about genes and their location on chromosomes helped transform biology into an experimental science." The centimorgan , a unit of recombinant frequency used in gene mapping, was named in his honor. External links http://www.columbia.edu/cu/alumni/Magazine/Morgan/morgan.html ...

Vaccine

... - rather than introducing a whole inactivated or attenuated micro-organism to an immune system, a fragment of it can create an immune response recombinant Vector - by combining the physiology of one micro-organism and the DNA of the other, immunity can be created against diseases that have complex ...
