The Pros And Cons Of Genetic Engineering

A genetically engineered or “transgenic” animal is an animal that carries a known sequence of recombinant DNA in its cells and which passes to its offspring. Recombinant DNA refers to DNA fragments that have been joined together in a laboratory. The resultant recombinant DNA “construct” is usually designed to express the proteins that are encoded by the genes included in the construct, when present in the genome of a transgenic animal. Because the genetic code for all organisms is made up of the same four nucleotide building blocks, this means that a gene makes the same protein whether it is made in an animal, a plant, or a microbe. The resultant recombinant DNA “construct” is usually designed to express the protein(s) that are encoded by the gene(s) included in the construct, when present in the genome of a transgenic animal. Because the genetic code for all organisms is made up of the same four nucleotide building blocks, this means that a gene makes the same protein whether it is made in an animal, a plant or a microbe. Genetic engineering also known as genetic modification, is a direct manipulation of a genome with the use of biotechnology.

Genomes are able to removed by using a nuclease, an enzyme capable of cleaving the phosphodiester bond between the nucleotide subunits of nucleic acids. New DNA may be inserted in the host genome by isolating and copying the genetic material that is desired by using molecular cloning methods. Any organism that goes through the genetic engineering is considered as a Genetically Modified Organisms (GMO). The process for the genetically modifying animals is a long tedious process. However, the new technology is allowing modifications to become easier and more precise. When genetically modifyi...

...encoded with magnetic particles. Both the tape and the genes can be copied (cloned), or edited (recombined).

Tapes tend to be relatively stable, while DNA is quite dynamic. In nature, genes are continuously modified, and DNA is commonly transferred within and between species. All living organisms contain genes that carry the hereditary traits between generations. To understand biotechnology, it helps to compare genes with video tape. Both DNA and video tape are long, linear strings of information. This information is encoded in a particular way -- the genes encoded with DNA and the tape encoded with magnetic particles. Both the tape and the genes can be copied (cloned), or edited (recombined). Tapes tend to be relatively stable, while DNA is quite dynamic. In nature, genes are continuously modified, and DNA is commonly transferred within and between species.
