Organisms carry out their lives through the instructions found in DNA, allowing information to be transferred from one generation to the next. It is vital for students taking AP Biology - and those who are in the field of science - to understand these principles behind the third big idea because it deals with DNA, the metaphorical manual to life. By venturing into the study of genes, one can learn about the processes that create life and when the need arises, how to save lives. When Ricki Lewis wrote her narrative science, The Forever Fix: Gene Therapy and the Boy Who Saved It, she went into detail on the concept of gene therapy (Lewis, 2013). The idea behind gene therapy, as she mentioned, is exactly as stated in the third big idea’s essential knowledge…
P 53 also known as “the guardian of the genome” is a tumor suppressor gene that works regulating the cell cycle and apoptosis. It is a very important gene since the lack of its action can allow the cells to divide an abnormal number of times and if action is not taken by the cell’s checkpoints, this could lead to cancer. The evolution of tumors associated with mutations in the p53 gremlin is not well understood and numerous researches have been completed trying to identify all of its characteristics. As all inherited gene mutations, p53 mutations are present in all somatic cells, but the effect of these mutations can have malignant effect on the cells.…
By studying the interactions between biological systems and its in environment, one can begin to understand why changes - be it on the molecular level or an entire population’s level - occur and the important role it takes in survival. This idea can be seen in Sharon Moalem’s book, Inheritance: How Our Genes Change Our Lives and Our Lives Change Our Genes, when he touches on the study of epigenetics. Epigenetics relates to the fourth big idea in how it expands on its underlying statement of essential knowledge 4.C.2, which states that “Environmental factors influence the expression of the genotype in an organism” (The College Board, 2015). Defined in the book as the study of how certain factors can alter gene expression in one generation and sometimes pass on these alterations, Moalem addresses epigenetics through his existing medical knowledge and various conducted studies (Moalem, 2014).…
The Hunting Ground is a documentary that presents the stories of Andrea Pino and Annie Clark, students of the University of North Carolina who were sexually assaulted. The film follows their story as well as the stories of other women as they seek justice while also presenting statistics on sexual assault at universities throughout the country and testimonies from a former Notre Dame police officer that dealt with a campus rape case. Opening with video segments of students receiving letters stating they had been accepted to prestigious schools, the film begins on a very relatable note for college students. The tone of the movie begins to turn sour as it presents the testimony of the women that had been sexually assaulted at the University of…
When a person go to a grocery store the only thing in their mind is that they are on a budget and in a schedule, therefore, they need to quickly pick up everything they need without thinking where it’s coming from. Once the individual has paid and makes their way back home, the thought of where their purchases have come from, doesn’t cross their mind. The documentary “Food Inc.” produced by Robert Kenner focuses on the nation's food industry. The main focus of this documentary is to tell the American people what’s on their food and what they are consuming. This documentary is also focus on the America's food corporations' desire for money that has results in the mass production of food that’s now affecting millions of people across the nation.…
Mutation in the silencing gene SIR4 can delay aging in S. cerevisiae Gene mutations that affect silencing at HM loci, telomeres and other regions of the chromosome have been shown to relate to stress resistance and aging in Saccharomyces cerevisiae. S. cerevisiae is a species of yeast in which goes through asymmetrical cellular division. Its lifespan is measured by the number of cellular divisions the mother cell is able to complete before death. In the research study by Kennedy et al, the researchers focused on yeast cells and how stress tolerance can extend lifespan through silencing genes, like SIR4. SIR4, a silencing gene, works with other SIR genes to form a SIR complex which regulates expression at regions on the chromosome.…
Survival of the Sickest by Dr. Sharon Moalem is a novel that investigates genetic disorders/ diseases and how they might have once facilitated our survival. This particular novel highlights a few disorders and diseases and delves into their history of how they might have benefitted the human race at some point. After all, Moalem comments, “It’s a book about life- yours, ours, and that of every little living thing under the sun” (ix). A common theme throughout the book is that biology will select for the disease that will kill you after several decades rather than allowing a disease that will kill you much sooner.…
For about three decades many scientists did not believe DNA contained genetic material because it was not seen as complex due to the fact not much was known about it yet, so many presumed proteins were the genetic material of life. It was not until scholars such as Frederick Griffith, Meselson-Stahl, James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin, Avery, McCarty, Erwin Chargaff and many more conducted experiments that would expose astonishing discovering that will lead to the understanding of DNA also known as the Race for DNA. It began with Frederick Griffith’s Experiment “Transforming Factor”, conducted in 1928 testing bacteria for pneumonia and injecting them into mice. He noticed something was being transferred from the smooth strain to the rough strain when he mixed them together; he did not know what…
In this type of environment, the genes that were once responsible for keeping us alive, are now the ones responsible for keeping us…
Since my first biology class in the eighth grade, the words “survival of the fittest” have embedded themselves within the folds of my brain. After being enchanted by Darwin’s research and brilliance, I never once doubted that phrase. Like any enlightening and thought provoking book does, however, “Survival of the Sickest” by Sharon Moalem, revolutionized my view of science and biology. This book must be read by anyone who has any interest in themselves or the world. Dr. Moalem explores the complex relationships between evolution, disease, and longevity in a way that begs the audience to never be content with our knowledge of medicine and biology.…
The world of today is one of high performance. Everyone strives to be bigger, faster, stronger, and more efficient. However, this is not limited to humans. In man’s power hungry frenzy, unbelievable technological and scientific advances are made all the time. This can become dangerous as technology and biology are being integrated.…
(Williams, D.R. & Mohammed, S.A. J Behav Med (2009) 32: 20. doi:10.1007/s10865-008-9185-0) Medical advances have made it possible for people to live longer and healthier than ever, yet these numbers still exists. In this essay, I argue that the…
“Nutrigenomics is the new strategy in nutrition research that will lead to its development towards Nutritional Science 2.0”(Nutrigene.4t.com). It also shows the relation of genotype-phenotype to define an individual 's personal health. This means that since nutrigenomics was developed after the 20th century, it has been restoring people’s health such as preventing diet-related diseases to create a nutritious lifestyle. The further rapid change in technology and evolution of ideas was investigated by “The Age of Molecular Medicine” pioneered by Linus Pauling, Watson and Crick that described the structure of DNA in 1953(UKEssays). Before the Human Genome project was developed, scientists did not have the knowledge of how DNA was operated.…
This opportunity allows doctors and scientists to investigate the working of human DNA and potentially find cures for the most deadly diseases known to man. There is potential for greatness in this field of study; it’s just the people unwilling to support it. The future of medicine and treatment of diseases relies on the advances made in human genetic engineering studies. The Human Genome Project, an organization devoted to determining the sequence of chemical base pairs that make up human DNA, completed a “rough draft” in the year 2003…
