Plant cells act as the Natures cheapest factory.

Transgenic plants and animals wikipedia. Of which plant-based vaccine production has received particular attention due to the numerous advantages it may offer. Transgenic plants potato and cotton were for the first time made available to farmers in USA. Transgenic plants are plants that have been genetically engineered a breeding approach that uses recombinant DNA techniques to create plants with new characteristicsThey are identified as a.

By the year 1998-99 five major transgenic crops cotton maize soybean canola and potato were in widespread use. Plants are the natural producers. TRANSGENIC PLANTS- The plant whose genome is altered by adding one or more transgenes are known as transgenic plants.

Usually ear tissue and blood are screened by polymerase chain reaction andor Southern analysis for the. Transgenic plants can produce a variety of proteins used in diagnostics for detecting and curing human and animal diseases in large scale with low cost. The foreign gene is constructed using recombinant DNA methodology.

These genes are passed on to the successive generations. 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. The foreign gene that is introduced is known as the transgene and the animal whose genome is altered is known as transgenic.

Contents Transgenic animals are more widely used for various purposes. A transgenic plant contains a gene or genes that have been artificially inserted. Transgenic plants are plants that have had their genomes modified through genetic engineering techniques either by the addition of a foreign gene or removal of a certain detrimental gene.

Applications of animal transgenesis may be divided into three major categories. Animal life is possible due to plants. The aim is to introduce a new trait to the plant which does not occur naturally in the species.
