Anthropology 1: Human Evolution Recombinant DNA technology is defined as a series of procedures that are used to recombine DNA segments. A recombinant DNA molecule is constructed from segments of two or more different DNA molecules. Under certain circumstances‚ a recombinant DNA molecule can enter a cell and replicate‚ either on its own or after it has been integrated into a chromosome. Some examples of DNA technology are the insertion of bacterial DNA into certain crops‚ cloning‚ and genetically

transfer information and instructions between cells in animals and plants. They regulate growth and development‚ controlling the function of various tissues. Like antibiotics‚ hormones can be produced and placed in animal feed‚ for example Bovine Somatotropin‚ which is given to cows to increases milk production. The use of hormones and antibiotics in animal feed has been a controversial topic for many years. There are obvious advantages and disadvantages with the use of such products. Farmers

small percentage of the whole. In 1998 Harvard Medical School released a study (as cited by Larsen‚ 1998‚ ¶ 1) showing evidence that a product known as Recombinant Bovine Somatotropin (rBST) increased the chances of humans developing cancer. Bovine Somatotropin is a hormone produced by cattle which is also known as Bovine Growth Hormone. The Recombinant status means it was synthetically produced using recombinant DNA technology. The synthetic chemical is injected into cows to stimulate milk

This harmful chemical is used as growth hormones to incite cows for dairy products such as yogurt‚ milk and cheese.

Genetic Modification Genetic modification is the same as genetic engineering and genetic manipulation‚ which is the use of modern technology to change or alter the genetic code of an organism. Genetic modification includes using genes from one organism and inserting them into another‚ however‚ genetic modification can also be altering the original gene of the organism without changing the genetic codes. Therefore a (GMO) Genetically Modified Organism is one whose genes were altered. Genetic modification

If a person from the 1940’s were to walk into a grocery store‚ chances are they would be utterly confused. The source of their confusion would be the labels that are on the food; rBGH and rBST treated cows‚ organic and natural are all terms that have become the norm over the past eighty years. The wellbeing of consumers‚ animals or the earth‚ does not seem to be a priority for food company heads‚ therefore change needs to occur in the regulations done by the FDA.

TRANSGENIC SPECIES SPEECH Good afternoon Ladies and Gentlemen. Today‚ the topic for our debate is on whether “the benefits of transgenic species outweigh the ethical considerations.” We‚ the negative team‚ believe that this statement is false. The first affirmative speaker has tried to tell you that transgenic plant species are a revolutionary new way to produce crops with dramatically increasing yields and as a result‚ this will increase the farmlands’ productivity. However‚ this is
