Legend: Example Technology:


Introduction of the gene encoding insulin in bacterial plasmids that


in turn carries the gene replication in bacterial cells, leading man


insulin. Plasmids: Plasmids are small circles of DNA found in cells of bacteria


separate from the bacterial chromosome and smaller than he. They are able to take


easily from one cell to another, even when the cells are clearly


different species, far apart on the evolutionary scale. So


plasmids can be used as vectors


,



playback allows foreign DNA by a bacterial replication system. cDNA human: genes consist of coding sequences and nekoduyuchyh. Copies of the coding sequences is called cDNA. It can be obtained from


reverse transcription of RNA. Transcription and translation of insulin cDNA will >> << production of functional molecules of insulin. Transfer of insulin gene Plasmid vector. Plasmids include both threads on, leaving a free, sticky end which DNA can be attached. Special communication sequences are added to human cDNA that he


fit exactly in the free ends opened plasmid DNA ring. Plasmids containing the human gene, also called recombinant plasmids,


ready to be inserted into another organism, such as bacterial cell >>. Recombinant plasmids << and bacterial cells are mixed. Plasmids


introduces bacteria in a process called transfection


. With the recombinant DNA molecule


successfully inserted into the bacterial host, the other object >> << plasmids can be used - their ability to multiply. After oral administration >> << bacteria, plasmids containing cDNA people can multiply to give


few dozen copies. When strattera 25mg bacteria divide, plasmids share


between the two daughter cells and plasmids continue to reproduce. Since


cell division rapidly (every 20 minutes), bacteria containing human


cDNA (coding for insulin, for example), will soon produce many millions


similar cells (clones) containing the same human gene. From: BIO. Biology in the future. Washington, DC: Biotechnology Industry Organization >> << 1990. .
