Genetics
Genetic engineering is an umbrella term that can cover a wide range of ways of changing the genetic material -- the DNA code -- in a living organism. This code contains all the information, stored in a long chain chemical molecule, which determines the nature of the organism. Apart from identical twins, genetic make-up is unique to each individual. Individual genes are particular sections of this chain, spaced out along it, which determine the characteristics and functions of our body. Defects of individual genes can cause a malfunction in the metabolism of the body, and are the roots of many In a sense, man has been using genetic engineering for thousands of years. We weren't changing DNA molecules directly, but we were guiding the selection of genes. For example the domestication of plants and animals. Recombinant DNA technology is the newest form of genetic engineering, which involves the manipulation of DNA on the molecular level. This is a totally new process based on the science of molecular biology, a relatively new science only forty years old. It represents a major increase in our a
The government has even approved the sale of certain products. This is cloned to make a batch of probes using the recombinant DNA into E. The corresponding colony on the original plate thus contains the bacteria carrying the required gene. But a negative aspect is that it changes the forms of life we know of, possibly damaging our environment It has been known for some time that genetic information can be transferred between micro-organisms. When the possible threats and the potentially helpful applications are weighed it appears that research into the possibilities should continue. It involves the introduction of a gene into somatic cells and enablement of its products to alleviate a disorder caused by the loss or malfunctioning of a vital gene product. Next, the plasmid is allowed to infect a bacterium, in which it can replicate. The next step is to make, on special filter paper, a replica of the plate with the colonies of the cloned bacteria. There is no possible way that it could truthfully be said that we haven't done so already. Transgenic technology bypasses conventional breeding by using artificially constructed parasitic genetic elements as vectors to multiply copies of genes, and in many cases, to carry and smuggle genes into cells that would normally exclude them. Often this is a plasmid, a selfreplicating circular piece of DNA that can become incorporated in the bacterial nucleus and later become detached, carrying genes with it. It does not take genetic medicine to increase our populations beyond what natural barriers had been in place, such as disease and famine.
