Matt is a history teacher. His twin brother Greg is a drug addict. Growing up in the Boston area, both boys did well in high school: they were strong students in the classroom and decent athletes on the field, and they got along with their peers. Like many young people, the brothers drank the occasional beer, smoked cigarettes and experimented with marijuana. Then, in college, they tried cocaine. For Greg, the experience derailed his life. The questions that have risen from this are: what made Greg so susceptible to the grasps of cocaine- to the point that the drug essentially destroyed his life? And how did his identical twin, who shares the exact same genes, escape a similar fate? And how can exposure to a drug set up some individuals for a lifelong addiction, while others can move past their youthful indiscretions and go on to lead productive lives? These questions, although not new, have lead neuroscientist to begin taking a fresh approach to finding the answers. New findings suggest that experience can contribute to mental illness by adding or removing “epigenetic” marks on chromosomes. These tags are particular chemicals that can influence gene activity without changing the information encoded in the gene.…
Epigenetics is a termed coined from epigenome. It is the study of occurrence of changes in the human genome as a result of gene modification expression raising from factors such as lifestyle. The PBS video presents the efforts and advancements made in epigenetics. It is fascinating to realize two people who are identical due to their DNA like twins turn up to be totally different due to alteration of their genes. Great effort has been dedicated in the study of epigenetics in an effort of curbing inherent diseases such as cancer. The breakthrough presented in the video sheds light in the fight against incurable diseases such as cancer as the realization that genes can be altered and modified by what people eat is an interesting breakthrough phenomena.…
How much do external circumstances really affect the overall outcome of each and every human life? It comes down to a mixture of genetics and the events that occur to shape how people live. Despite the importance of genetics, throughout history, it has been proven that the environment has a greater impact on who a child becomes. There are genetic factors that may result in a bias, such as mental health and disabilities, as well as issues that can occur while developing as a child, but for the most part, these can be minimized with positive influence and encouragement. Parent’s decisions shape how their children may react to different situations.…
The geneticists mentioned that he is trying to give the parents the”best possible start” and that the child will be the “best of you.” I think people are misunderstanding that the child is the best of you, but not the best human being, because we are not perfect. Imperfection is what makes human unique. This shows that the genetic traits are the potential guides or the “start” of life, but people can still change due to their living environment. Sometimes I think gaining too much control of things makes it too complicated and it is better to leave it to nature and chance, just like how the parents in the film wanted some traits to be…
It can be argued that the discovery of DNA has been an extremely beneficial ordeal. Yes, the genetic makeup of an individual can now be found. Yes, knowing the genetic makeup of an individual can even save their life. But the big question is, will the genetic makeup of our next generation shape their lives, devastate their dreams and leave them feeling "invalid" or second rate to…
Genetically modified foods are beneficial for our society because of the nutrients that may be added to foods and the greater ability to produce these foods. While some people argue that genetic modification is still a new technology that should be researched further, others will agree that the benefits definitely outweigh the drawbacks. Society today has all kinds of new technology at its fingertips and should be allowed to use this technology to enhance certain things to better the world.…
* 1) A majority of genetically engineered crops in production worldwide today have been engineered with a gene that:…
Genetic engineering (GE) is also known, as genetic modification is the process of organisms that are genetically modified. In this process the goal is to transfer new DNA to an organism so it can improve its habits and make new cells.…
Genetic engineering often gets a bad rap with changing the natural evolutionary cycle, but it could, with proper guidance, improve almost every aspect of daily life. Advances in the Biotech Revolution have made many things that we had merely considered to be science fiction or a thing of dreams are now possible.The fact of the matter is that genetic engineering is applicable to everyday life while still being ethical and inline with people’s morals.…
This relates to what we are doing in class because we are speaking about genes and genetics. We’re also learning about genetic disorders which happen when one person is missing a chromosome or has an extra chromosome. Examples can be Down syndrome or Turner Syndrome. This also relates to punnett squares. In punnett squares you find the probability of characteristics and you can use one to find out the probability of a person developing alcoholism. This article relates to class and can possibly relate to anybody’s life. This article taught me that alcoholism is a genetic “disease” and is not something to take lightly. It also helped me learn how traits are passed down through generations and it will continue as long as that gene is in the…
Some believe that the concept is simple. Utilizing potential knowledge of the impending future, we are given the chance to think and to prepare. We are given the chance to absorb the entirety of the situation and consult a genetics counselor. With prior knowledge we could save people years of suffering and financial trouble.…
In “My Genome, My Self,” Steven Pinker wrote about how he was getting his genome tested and where exactly personality traits came from. I thought that this essay was very interesting because it had a lot of information in it, with facts from all different sides of the spectrum. Pinker talked about the sciences of how geneticists proved that every trait a person can have can be linked to genes. He also talked about some part of personality traits are part environmental, yet not the majority. Last he mentioned the “brute chance” of traits coming and growing into a person.…
Brain development is an elaborate process, including neuron proliferation, differentiation, migration, communication, and apoptosis. Hereditary deficits and negative environmental exposures can lead to irregular neurological development. The characteristics of neurodevelopmental disorders firmly coincide with the qualities of dysfunctional epigenetic adjustment at the chromatin level, exclusively or in collaboration.…
One of the bioconservation arguments focuses is on the idea of unpredictable results. You could ask for your kid to be born with blue eyes but when the baby is born it has brown eyes. Sometimes even when you select the correct genes of the person sometimes things do not work out. The genetics sometimes take over and override what you expected to happen. Also, sometimes the person that selected the genes could have selected the wrong set of genes and that could change the results you…
