Transgenic Animals Are Those Which Have Foreign Dna In

Recombinant dna technology is used for this purpose. The vast majority of genetically modified animals are at the research stage while the number close to entering the market remains small. These are animals that have been genetically modified through the introduction of foreign dna or rna.

The transgenic animals are those which have (a) foreign rna in all its cells (b) foreign dna in some of its cells (c) foreign dna in all its cells (d) both (a) and (c).

Transgenic animals are those which have foreign dna in. The main principle in the production of transgenic animals is the introduction of a foreign gene or genes into an animal (the inserted genes are called transgenes).the foreign genes must be transmitted through the germ line, so that every cell, including germ cells, of the animal contains the same modified genetic material 18. Most common m ethods used to produce transgenic animals is the inj ection of foreign dna seq uence into the pronucleus of recently fertiliz ed zygotes. Transgenic animals are created by deliberately inserting a gene into the genome of an animal.

Transgenic animals are those animals which are genetically modified using recombinant dna technology. The transgenic animals are those which have (a) foreign dna in some of its cells (b) foreign dna in all of its cells (c) foreign rna in all of its cel A transgenic, or genetically modified, organism is one that has been altered through recombinant dna technology, which involves either the combining of dna from different genomes or the insertion.

Ruddle (1981), there has been rapid development in the use of genetically engineered animals as investigators have found an increasing number of applications for the technology. This results in the second organism and its descendants being grouped as transgenic animals (cloned organisms). 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.

Much recent research has concentrated on engineering ti plasmids to contain other genes that are also transferred to the host plants during infection, creating transgenic plants. Such animals are most commonly created by the microinjection of dna into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a pseudopregnant surrogate mother. In transgenic animals how foreign gene is introduced in all the cells??.

Transgenic animals are those that have been genetically modified. The simplest type of transgenic animals are those which have genetic material inserted into their own code for research purposes. The transgenic animals are those which have (a) foreign dna in some of its cells (b) foreign dna in all its cells (c) foreign dna and rna in some of its cells (d) foreign dna and rna in all its cells

Methods for producing transgenic animals: They have had their dna altered specifically by having the dna of another animal inserted into their own code, in contrast to cisgenic animals, which have their dna altered by other means. The production of pharmaceuticals using transgenic animals is called _____ _____ gene pharming.
