I to obtain information on gene function and regulation as well as on human diseases ii to obtain high value products recombinant pharmaceutical proteins and xeno-organs for humans to be used for human.

Transgenic plants and animals wikipedia. Applications of animal transgenesis may be divided into three major categories. Transgenic animals for the production of therapeutic and diagnostic proteins are produced by transferring fertilized transgene-carrying embryos to recipient animals. Following natural gestation and birth offspring are subject to tissue biopsy and blood sampling.

Usually ear tissue and blood are screened by polymerase chain reaction andor Southern analysis for the. 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. Transgenesis is the phenomenon in which a foreign gene with desired characteristics is introduced into the genome of the target animal.

The monoclonal antibodies peptide hormones cytokinins and blood plasma proteins are being produced in transgenic plants and their parts such as tobacco in leaves potato in tubers sugarcane in stems and maize in. Transgenic plants are the ones whose DNA is modified using genetic engineering techniques. Plant cells act as the Natures cheapest factory.

A foreign gene will be inserted into a plant of a different species or kingdom. Although several recombinant proteins used in medicine are successfully produced in bacteria some proteins require a eukaryotic animal host for proper processing. Plants are the natural producers.

By the year 1998-99 five major transgenic crops cotton maize soybean canola and potato were in widespread use. TRANSGENIC PLANTS- The plant whose genome is altered by adding one or more transgenes are known as transgenic plants. For this reason the desired genes are cloned and expressed in animals such as sheep goats chickens and mice.

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. 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.
