Transgenic Plants And Animals Wikipedia

Transgenesis is the phenomenon in which a foreign gene with desired characteristics is introduced into the genome of the target animal.

Transgenic plants and animals wikipedia. Transgenic plants are the ones whose DNA is modified using genetic engineering techniques. The very purpose of production of transgenic plants is for their commercial importance with high productivity. A transgenic plant contains a gene or genes that have been artificially inserted.

The foreign gene that is introduced is known as the transgene and the animal whose genome is altered is known as transgenic. TRANSGENIC PLANTS- The plant whose genome is altered by adding one or more transgenes are known as transgenic plants. It was in 1995-96.

Although several recombinant proteins used in medicine are successfully produced in bacteria some proteins require a eukaryotic animal host for proper processing. Applications of animal transgenesis may be divided into three major categories. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.

Plant can be used as bioreactor transgenic plants which can be used to produce the proteins or peptides encoded by the introduced foreign genes in vaccine production against animal and human diseases. Plant cells act as the Natures cheapest factory. Plants are the natural producers.

The foreign gene is constructed using recombinant DNA methodology. Transgenic models are more precise in comparison to traditional animal models for example the oncomouse with its increased susceptibility to tumor development enables results for carcinogenicity studies to be obtained within a shorter time-frame thus reducing the course of tumor development in experimentally affected animals. Usually ear tissue and blood are screened by polymerase chain reaction andor Southern analysis for the.

Transgenic plants are also called Genetically modified crops. By the year 1998-99 five major transgenic crops cotton maize soybean canola and potato were in widespread use. The cell uses CO 2 water minerals and sun light to synthesise thousands of valuable and complex products which are the basis of animals life.
