Transgenic Plants And Animals Wikipedia
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 and animals wikipedia. Transgenesis is the phenomenon in which a foreign gene with desired characteristics is introduced into the genome of the target animal. The foreign gene that is introduced is known as the transgene and the animal whose genome is altered is known as transgenic. Although several recombinant proteins used in medicine are successfully produced in bacteria some proteins require a eukaryotic animal host for proper processing.
Following natural gestation and birth offspring are subject to tissue biopsy and blood sampling. Transgenic plants are also called Genetically modified crops. Applications of animal transgenesis may be divided into three major categories.
A transgenic plant contains a gene or genes that have been artificially inserted. By the year 1998-99 five major transgenic crops cotton maize soybean canola and potato were in widespread use. A foreign gene will be inserted into a plant of a different species or kingdom.
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. The very purpose of production of transgenic plants is for their commercial importance with high productivity. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.
Plants are the natural producers. Transgenic plants are the ones whose DNA is modified using genetic engineering techniques. Plant cells act as the Natures cheapest factory.
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. 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. For this reason the desired genes are cloned and expressed in animals such as sheep goats chickens and mice.
