article on gene therapy. Hayes is a visiting scholar at the University of California at Berkeley and has a Ph.D. in Energy and Resources. He has also addressed the United Nations about banning human cloning worldwide. The author argues against using genetic therapy in human research because of the risk it provides for human rights. He believes that it will likely result in the escalation of social inequality. Hayes is wrong‚ but also right at the same time. He is right about how gene manipulation

modifications referring to “altering the genetic trait of a living organism by using recombinant deoxyribonucleic acid (DNA) technology to transfer one or more genes from one organism to another by crossing biological species.”[65] New developments in molecular and cell biology allow scientists to modify foods by the identification‚ copying‚ and insertion of genes into plants. It can whether be a good or bad thing depending on a lot of personal beliefs and opinions. http://www.csa.com/discoveryguides/gmfood/overview

An overview of several important discoveries on the nature of gene: In the 1860’s Mendel discovered the discrete units of inheritance. 1880’s: discovery of chromosomes. 1903: discovery of homologous chromosomes. 1909-1911: discovery of crossing over. 1911: discovery that genes could be mapped in order along length of chromosomes. 1944-1952: discovery of DNA as genetic material. 1953: Watson and Crick discovered DNA

as further advancements in treating the illness‚ the revolutionary discovery of the cystic fibrosis trans-membrane conductance regulator gene was made‚ by the scientist who would later go on to completing the Human Genome Project‚ In 1989. A mutation of this gene directly causes Cystic Fibrosis. Not too long after the discovery of the Cystic Fibrosis gene‚ gene replacement therapies began as a new treatment method during the 1990’s. Finally during the 1990’s the first drug made to treat Cystic Fibrosis

Huntington ’s disease John Doe HCS/245 10/20/2013 Prof Jane Huntington ’s disease In 1993 researchers discovered the gene that causes Huntington’s disease. (Huntington ’s disease Society of America‚ 8/27) Huntington’s disease is a disease which progressively degenerates cells in the brain slowly over time. Since the nerve cells in the brain are slowly dying it causes uncontrollable movements‚ emotion changes and other forms of determination of psychological aspects. (The Diagnosis and

series of the nucleotide makes up the genes. The sequence of the nucleotides determines each of our 20‚000 different genes. Every 3 nucleotides codes are for a specific amino acid. The amino acid sequence determines what protein will be made. The proteins acting as enzymes will determine our physical traits like eye color‚ number of bones‚ blood type....etc. B. The most important findings of the Human Genome Project are so many nucleotide bases and the genes contained in the human chromosomes.

there are also other options in which parents can deal with a mutation in a gene on chromosome 4 in a fetus. However‚ there is also a legitimate ethical dilemma between the two parents and the genetic counselor. Because the parents had a child with two such genes die at 2 months old‚ they want a baby who is heterozygous for the achondroplasia trait. Unfortunately the child inherits a flawed gene from one parent and a healthy gene from the other parent‚ so the child will be a dwarf just like the parents

cloning. Cloning is a natural process‚ many living things only need one parent to reproduce‚ this process is called asexual reproduction; for example single-celled bacterium use this process. The new bacteria inherits its genes from only one parent‚ this means that their genes are identical to their parents. Genetically identical organisms are called clones‚ if there is any variation between them will be caused by differences in their environment. Plants have unspecialized cells; these cells are

slightly lighter blue than its surroundings in the sixth lane. This smear is the plant chloroplast gene‚ which barely showed up on the positive control(Lane 2) and lanes 5 and 6. Lane 1 was the ladder‚ which showed DNA fragments of different sizes so we could compare. The third lane is the negative control‚ which was DNA that was known to not have genetically modified genes. The plant chloroplast gene showed up in this lane. However‚ it did not show up on the first group’s lane‚ and this was probably
