Genetic Engineering, the manipulation of an organism’s genetic makeup, has been around ever since the 1968 discovery of restriction enzymes (“Genetic Engineering”). Those that are genetically manipulated are known to be GMOs (Genetically Modified Organisms). Scientists first started by genetically modifying bacteria (“Genetic Engineering”), and as technology and research advanced, so did genetic engineering. Scientists can now genetically modify several organisms, including plants and food. One of

Although the DNA in our genes is considered to be the heritable genetic material, other factors, including the environment are considered to play an important role in the activity and expression of those genes. Summarize the role that epigenetics & developmental epigenetics play in health & disease. Epigenetic modifications are a dynamic process reflecting a complex interplay between an organism and its environment. For example, the acetylation of lysine residues in histone subunits usually can

for its use in genetically modified foods. DNA fragments that code for better tasting, higher nutrient qualities are spliced into regular plants to produce super foods (US Dept of Energy Genome Program, 2009). Reproductive cloning takes all the genetic information out of a cell and replaces it with DNA from the desired organism. With luck, this cell will begin to divide until it becomes an embryo and can be implanted into a host mother (US Dept of Energy Genome Program, 2009). Gene Therapy and

Human Genetic Engineering Imagine being able to design your own baby before it is even born, or prevent your unborn child from a dreadful disease, or make your baby a genius or an athlete. Scientists could be opening Pandora’s Box with the potential development of human genetic engineering. Genetic engineering is the process by which genes are added or transferred to alter the genetic code of an organism (“What is Genetic Modification”). Since the completion of the Human Genome Project in 2006

The United States government needs to add regulation for the use of genetic engineering, considering the effect on human genetics in future generations, how it adds to the social-economic divide, and lastly how this

What is genetic engineering? Genetic engineering involves manipulation of cellular material to create changes in the structure of living organisms. Altering the DNA of a cell changes the attributes of cells created by later reproduction, ideally in a useful and beneficial way. The process is used to create plant or animal hybrids, to correct genetic flaws in an animal or human, or to utilize biological organisms to produce valuable chemicals (such as insulin). What are the concerns? While

necessary to investigate how the variability present in a population behaved across generations. Thomas Hunt Morgan, who was a geneticist and embryologist of that era, was one of the first to explain the genetics based on the laws of Gregor Mendel, who was known as the creator of the science of genetics for his experiments in plants. He used in his study the Drosophila melanogaster, which is a species of fly that is known as the fruit fly as it is found feeding on fruits that are in the fermentation
