genetic conditions. The current on-going research is in the field of gene therapy‚ an experimental technique that uses genes to treat and replace the defective genes of an affected person. Instead of treating disease symptoms‚ this has the potential to correct the underlying cause (1). Besides its high costs and ethical concerns (therapy involving germ line treatment)‚ this technique also poses a considerable amount of risk. Thus‚ gene therapy is currently only being tested on the diseases for which

While gene therapy holds promise as a revolutionary approach to treating disease‚ ethical concerns over its use and ramifications have been expressed by scientists and lay people alike. For example‚ since much needs to be learned about how these genes actually work and their long-term effect‚ is it ethical to test these therapies on humans‚ where they could have a disastrous result? As with most clinical trials concerning new therapies‚ including many drugs‚ the patients participating in these studies

Averi Bates 4th Should Gene Editing Be Performed on Human Embryos? Gene editing is the changing of the human genome through artificial means like CRISPR. It has several possible outcomes both positive and negative. Some possible positive outcomes would be the eradication of genetic diseases and the genetic enhancement of humanity becomes more genetically perfect beings‚ the negatives would include the creation of horrible defects that replace those eradicated diseases or the creation of designer

W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

a fault in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on chromosome 7 at q31.2. For CF to be expressed‚ a faulty copy of the gene must be present at both alleles; autosomal recessive. Therefore both parents must be carriers of‚ or affected by the cystic fibrosis gene (fig. 1) for the gene to be passed on. If a person has one copy of the faulty allele (are heterozygous) they are carriers of the gene and can pass this allele on; if they possess two copies of the faulty allele

of inheriting the gene‚ which will in turn will eventually lead to the onset of the disease (Oster‚ Shoulson‚ & Dorsey‚ 2013). It is the neurodegeneration of the brain‚ but have more specifically been found in the basal ganglia and cerebral cortex (de Paula‚ Concalves‚ & Vieira‚ 2015). The huntingtin gene (HTT) is the instruction manual to produce the protein huntingtin‚ which helps neurons in the brain to function (Huntington disease‚ 2016). The mutation is in the HTT gene in the DNA segment

dominated by science. It seems that everyday‚ a new controversial topic appears. Most recently‚ the controversial topic is human germline gene therapy and this type of therapy does not have a place in 2016. I am against germline gene therapy because it is too early for human research‚ we as the science community do not know enough about the process of how genes control phenotypic expression‚ and if the technology to edit germline cells would be leaked to the public it could create an entirely new

Gene therapy was introduced into the scientific field around 1972‚ which led to the first attempt at its use in 1980. Although original efforts were unsuccessful‚ this event ignited research into the idea‚ which has led to the multiple developments in gene therapy still being refined today. Around the same time‚ biotechnology also emerged as a new and ingenious tool in field of biology which only furthered the potential abilities of gene therapy. Current research surrounding these fields combines

“Ghost in Your Genes”- when hearing this I thought of something unknown‚ overtaking your body‚ or at least a part of your body. The movie‚ Ghost in Your Genes‚ presents an experiment done in the 1990s‚ called the Human Genome Project (Ghost in Your Genes). During this project‚ researchers were able to discover the chemical structure of each gene and overall they hoped to find a cure for all diseases‚ such as alzheimer’s and autism (Ghost in Your Genes). It was also found out that humans‚ surprisingly

Genetics X143 Professor Yund 4.23.13 How do genes generate the Phenotype? “Every aspet of an organism is determined or influenced by the genes of the organism” What genes are‚ what they do‚ how they interact with eachother and the enviroment to generate a phenotype. Genes are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are
