Transgenic Animals Are Those Which Have Foreign Dna In

DNA and RNA both in the cells.

Transgenic animals are those which have foreign dna in. Transgenic animals are those that have been modified to express recombinant DNA from another species. It is most frequently achieved by integration of doned DNA sequences following their injection into the fertilised egg. Now adays it is possible to alter genes of plants bacteria or viruses to get.

Foreign DNA is introduced into the animal using recombinant DNA technology and then transmitted through the germ line so that every cell including germ cells of the animal contain the same modified genetic material. This fertilized egg divides mitotically to form the whole organism so. It is most frequently achieved by integration of cloned DNA sequences following their injection into the fertilized egg.

Transgenic organism is one that has become transformed following the introduction of novel genes into its genome. Transgenic animals are those that have a transferred or altered DNA incorporated taken from related or unrelated species in their genetic line. The foreign gene that is introduced is known as the transgene and the animal whose genome is altered is known as transgenic.

This gene when expressed may. The major ones are micro-injection embryonic. 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.

Transgenic plants can be made by introducing foreign DNA into a variety of different tissues. Transgenic Animals A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. Theoretically all living beings can be genetically manipulated.

Transgenic sheep and goats have been produced that express foreign proteins in their milk. Transgenic animals can be used to generate innovative technologies efficiently than they were to be produced naturally. To reach this goal the foreign gene can be transferred using different methods according to animal species Vithani 2008.
