What is GM product and how the gene is modified?



In fact, the GM products are not as horrible as imagined. It is said that scaring comes from lacking of the knowledge. Wanting to know whether GM products can benefit or harm for the human being, we should understand some concepts about it.

Simply, GM can be understood as a process that moving away a part of gene of the creature, which is predicated that is not good for the human’s health or does not adapted the environment very well, from its chain of gene; then embedding another part of gene took from the other specie, which is regarded as possessing the particular property opposite the former one, into this genetic chain. In a word, “GM is a special set of technologies that alter the genetic makeup of organisms such as animals, plants, or bacteria.”(U.S. Department of Energy)
The products used this technology to generate are called GM products. Generally, there are three methods which can help the modified gene invading into the cells of the products: bacteria, stream electricity and gene gun. Consequently, GM products are created.
The key point in this technology is GM can be adopted between no-related spices. As the above case, Asresearch is introducing the genes of human proteins into GM cows and expect to gain the medicinal milk to treat the human’s disease. Furthermore, the GM technology differs from the traditional hybrid breeding since it extremely shortens the time for selecting the excellent species according to the human’s necessary. No doubt, this invention strengthens the opposability of human to the nature.

Even though these Atlantic salmon are roughly the same age, the big one was genetically engineered to grow at twice the rate of normal salmon.
