Gene expression

typically have a higher chance of being born with the gene that causes HD, while those of Asian and African background have a lower probability. For HD to be developed only one copy of the mutated huntingtin (HTT) gene must be inherited. Overall, individuals affected by this disorder experience an array of symptoms eventually impairing their ability to function and in most cases limit their lifespan by fifteen to twenty years in adults. In humans, the gene HTT that codes for the protein…

In Inheritance: How Our Genes Change Our Lives and Our Lives Change Our Genes, author Sharon Moalem uses a concoction of historical happenings, real-life experiences, and patient case history to portray two main biological concepts: deviations from Mendelian genetics and epigenetics (Moalem, 2014). In regards to the AP Biology curriculum, these two concepts relate, respectively, to the third and fourth big ideas that make-up the course’s framework. The third big idea in the AP Biology…

Genome targeting and editing has provided the ability to better understand and determine the function of genes in many model organisms. Genomes are composed of genes which are the basic unit of heredity that determine the traits organisms express. With the ability to target specific genes and edit them, genes and their locations in the genome can be studied and determine their significance and function, in addition to gaining an understanding to human disease and possible routes to eliminate…

genetics and environment together can cause the onset of anorexia. There are two ways this can happen. One is gene-environment interaction, which basically means that if a person has a certain gene and is placed in the right environment, then that gene could be activated and could potentially cause anorexia. The other way is epigenetic effects. This is when the environment changes gene expression and can alter the phenotype (Culpert et al., 2015). There have been studies on these types of…

Sperm containing the Y chromosome with a properly functioning SRY gene determines male gender, and if contains the genetic material of the X chromosome is shaped female. The presence of the SRY gene is the basic criterion of gender gene in humans. Discovered in 1990 by a group of P. Goodfellow from the University of Cambridge ,SRY gene is called the "central switch of the masculinity" and is located on the short arm of the Y chromosome locus…

Description or Technology: Gene therapy is an experimental technique that uses gens to help prevent or cure/treat diseases found in the body. It changes the expression of how a person’s genes function. This technique is the future of allowing doctors to use a corrected gene by simply inserting it into the patient’s cells to treat disorders and help make the organs work properly. This minimizes the need to use drugs or perform surgery. This technique is risky, and is still undergoing…

Abstract Tafazzin, encoded by the TAZ gene, is a mitochondrial membrane-associated protein that remodels cardiolipin (CL), an important mitochondrial phospholipid. CL is essential for proper mitochondrial structure and function, ensuring proper functioning of energy production and apoptosis. TAZ mutations are associated with the X-linked metabolic disorder, Barth syndrome (BTHS). BTHS is a lipid metabolic disorder that affects mitochondria that is often fatal in infancy and early childhood, due…

In Vitro Fertilization and Cas9 By Cody Dyess ENC1102 Professor Rivers 11/20/17 Outline I) Introduction A) Gene therapy B) Thesis statement: Cas9 should be used for gene therapy in in vitro fertilization to stop genetic disorders from developing in children. II) Defining what Cas9 is III) The history of Cas9 IV) Defining in vitro fertilization and its history A) Discovery B) Implementation V) Merging Cas9 with in vitro fertilization VI) Results of Cas9 against disease VII) Cas9’s…

Genetically modified organisms (GMO’s) have replaced our diet with genetically altered foods, which have adversely affected human health as well as local communities. Genetically modified organisms (GMO’s) are a broad group of plants, animals, and bacteria that are engineered for a wide variety of applications ranging from agricultural production to scientific research. The types of potential hazards posed by GMO’s vary according to the type of organism being modified and its intended…

author who specializes in the fields of rare diseases, neurogenetics, and biotechnology. His three books Survival of the Sickest, How Sex Works: Why We Look, Smell, Taste, Feel, and Act the Way We Do and "Inheritance: How Our Genes Change Our Lives—And Our Lives Change Our Genes" offer an engaging and revolutionary way of thinking as to why humans are the way they are, and why life is the way it is. Survival of the Sickest in particular is an incredibly intriguing book that explores the reasons…
