Transgenic Plants And Animals Wikipedia

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.

Transgenic plants and animals wikipedia. Plant cells act as the Natures cheapest factory. Usually ear tissue and blood are screened by polymerase chain reaction andor Southern analysis for the. Transgenic plants potato and cotton were for the first time made available to farmers in USA.

A transgenic animal is one that carries a foreign gene that has been inserted into its genome. It was in 1995-96. 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.

These genes are passed on to the successive generations. Transgenesis is the phenomenon in which a foreign gene with desired characteristics is introduced into the genome of the target animal. Of which plant-based vaccine production has received particular attention due to the numerous advantages it may offer.

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. In addition to the gene itself the DNA usually includes other sequences to enable it to be incorporated into the DNA of the host and to be expressed correctly by the cells of the host.

Following natural gestation and birth offspring are subject to tissue biopsy and blood sampling. Transgenic plants and animals Transgenic plants are plants that have been genetically engineered a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. 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. The very purpose of production of transgenic plants is for their commercial importance with high productivity. For this reason the desired genes are cloned and expressed in animals such as sheep goats chickens and mice.
