Transgenesis is that the process of introducing a gene (referred to as a transgene) from one organism into the genome of another organism. The aim is that the resulting transgenic organism will express the gene and exhibit some new property or characteristic. Transgenic may be a term that describes an organism containing genes from another organism put into its genome through recombinant deoxyribonucleic acid techniques. the method of introducing an exogenous gene is named transgenesis. one among its essential applications is for experimental research processes. Transgenesis refers to the method of introducing transgene (i.e. an exogenous gene) from one organism into another with the intent of enabling the latter to exhibit a replacement property which will be transmitted to its offspring. A transgenic organism is one that contains genes from other organisms. These genes usually add some special ability or function to the organism. Soybeans are engineered to contain Glyphosate-resistance genes, and other crops are engineered to grow well in soil with high salt concentration. Generating a typical transgenic construct involves assembling three basic DNA elements: (1) a promoter and/or enhancer which confers the specified spatial and temporal pattern of transgene expression; (2) the gene to be transcribed, which can or might not encode a protein; and (3) a transcription termination.Transgenesis. (also called genetic modification) Transgenesis is that the process of introducing a gene (referred to as a transgene) from one organism into the genome of another organism. The aim is that the resulting transgenic organism will express the gene and exhibit some new property or characteristic. Transgenesis may be a mode of experimentation involving insertion of a far off gene into the genome of an organism, followed by germ-line transmission of the gene and analysis of the resulting phenotype within the progeny.
