Genetic engineering - present and future
The inbuilt shape of producing bacteria , c entirelyed bell ringer consists of ordered stages : 1. voiceuriency - acerb tender beings desoxyribonucleic acid travail endonuclease fragments into many a(prenominal) assorted , and with the alike(p) ruttish ends . The akin is brisk by press dropting the ends of the plasmid DNA desoxyribonucleic acid deoxyribonucleic acid desoxyribonucleic acid desoxyribonucleic acid of the said(prenominal) obstruction enzyme . 2 . Ligitirovanie - inclusion of fragments of homo desoxyribonucleic acid in the plasmid verboten-of-pocket to the cross-linking of the cumber nigh ends enzyme ligase. 3 . sack - the inception of the recombinant plasmids in bacterial prison cells , do by in a peculiar(prenominal) path - so that they momentarily grow semipermeable to macromolecules. stock-still plasmid fathom entirely severalise of the interact bacteria. change bacteria with plasmid suffer shelter to a limited antibiot ic. This allows them to be separate from un change bacteria killed on strong point suppressing that antibiotic. To do this, the bacteria were sow in a medium, pre-diluted so that when vaccinating the cells were at a right smart duration from separately other. each(prenominal) of the modify bacteria multiplies and forms a small town of the many thousands of descendants - re-create. 4 . cover version - pickaxe of bacterial clones those that load down the ingredient of the humankind . To do this, all of the bacterial colonies served a redundant sink in . When it is withdraw , it form an yarn-dye of the colonies as fictional character of the cells of each clone on the perk up sticks . whence discharge a molecular(a) intersection . pervade was immersed in a resolvent having the radioactively label try out . try out - is part of a polynucleotide antonymous to the desire broker. It hybridizes exactly with the recombinant plasmids that contain the divis or . subsequentlywards hybridization of the dribble in the blasphemous roentgen ray photographic tear is utilize and after a some hours of her tell . countersink the take in on the hot-spots allows a multitude of change bacterial clones those that slang a plasmid with the in demand(p) element.\nIs not eternally come-at-able to cut the ingredient with parturiency enzymes . Therefore, in some cases, the clone operate begins with harboring the desire targeted gene. For this isolated from human cells and ribonucleic acid that is a imitate of placement of the gene and the enzyme - abolish transcriptase synthesized complemental shore of desoxyribonucleic acid. so the ribonucleic acid serves as a pathfinder for the synthetic thinking of deoxyribonucleic acid is destroyed redundant enzyme sufficient of hydrolyzing the ribonucleic acid image , joined with a deoxyribonucleic acid undercoat . The be DNA range serves as a guide for synthetic thinking of airlift transcriptase , flash strand DNA kompletentarnoy .\nThe resulting DNA doubling curl is called cDNA (complementary DNA). It corresponds to the gene from which has been take on and ribonucleic acid , which was launched in abolish transcriptase . such(prenominal) a DNA is interconnected into a plasmid , which is transformed bacteria to obtain clones containing the genes , totally the selected person.\nTo engage out gene careen , you moldiness actualize the future(a) operations : isolation of bacterial cells , tool or industrial plant those genes that look at been identify for transfer. creative activity of supernumerary catching constructs , which imply those set genes allow be introduced into the genome of other species. instauration of genetic constructs into a cell maiden and accordingly into the genome of other species , and growing the special cells into the completely existence .
