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

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

“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

mutate gene out of the embryo and replacing it with a healthy unmutated gene. This is remarkable because with this discovery we can cure a lot of single gene diseases such as Huntington’s Disease‚ Cystic Fibrosis‚ Tay-Sachs disease‚ and breast cancer‚ these are a few examples of the single gene diseases that can be cured with this gene editing. Diseases that are not able to be cured by the replacement of these genes are the much more complex diseases that contain hundreds and thousands of genes such

Those people are labelled valids and those with defects such as vision‚ hearing or general
