Epigenetics

Biology plays quite a lot on personality, people can be more likely to develop certain personality traits because they inherited them genetically. That is what biological psychologist’s study’s. There is an entire field of science called epigenetics that is all about how changes in behavior due to experience can affect people on a biological level and cause changes in genetics across generations. It’s far from the only thing that influences personality but it plays the part. Heredity plays a…

Epigenetics means changes in genes that do not affect DNA sequence. These changes might be affected by the exposure every human being has to a different environment and circumstances which leads to changes in their genes, yet these changes do not change that person’s DNA. After interviewing my family, I discovered that I am most at risk for asthma, dust and humidity allergy, rheumatoid arthritis, glaucoma, diabetes, hypertension and migraine. Having a twin sister helps me understand the meaning…

to their potentially harmful effects. In a seminar given on October 9, 2015 by Dr. Mahua Choundhury, Dr. Choundhury discusses the overall effects that plasticizers can have for the body’s processes. She takes an epigenetic viewpoint when discussing the effects of plasticizers. Epigenetics are heritable changes of gene expression that does not involve the actual changing of the genetic sequences and are the product of outside, environmental influences. Choundhury focuses more on the consequence…

offspring/upcoming generations. This is called Behavioral Epigenetics. Through either psychological, physical, or emotional changes, everything we do, we think, or even the way we act and the things we experience not only effect our DNA but also effect the DNA of future generations and their offspring, which sheds a light onto one question: Were our mothers right? Are we really what we eat? Background: By definition, Behavioral Epigenetics…

change and develop uniquely. However, there are set behaviors that are important to develop at particular times. These behaviors are genetic, but, are heavily influenced by people surrounding the individual. This can be explained by Erik Erikson’s epigenetic principle. The principle consists of eight stages, they span a person’s life, starting with birth and ending in death. Each stage has the same type of criteria: age, a particular task, a psychosocial crisis, a positive outcome, and…

Epilepsy is a disorder defined by many as having recurrent and unprovoked seizures (apgar pg 296). These seizures can range from very physical and dramatic seizures to light twitches or no movement at all (kirka…). Despite the obvious physical issues of this disease, its problems start in the brain, and the seizures are usually categorized by where they affect the brain. There are generalized onset seizures, which start on both sides of the brain, focal onset seizures, which start in one…

Peeke, “Epigenetics Transformation- You Are What Your Grandparents Ate”, Dr. Peeke’s talks about how your genetics determine your destiny, also based on what you and born with. If you are born with an obese trait or addicting trait you can dampen it by the way you eat and through your lifestyle. Dr. Peek also brings up if that your grandparents smoked you had a big risk of their children and grandchildren being obese. She brings up Epigenetics transformation research and how…

Epigenetic changes are those heritable changes in gene expression that do not involve any changes in a gene sequence (Holliday 2006). To put it simply, the DNA sequences coding the gene are not altered. Instead, the environment around the DNA is altered. The epigenome is the total sum of the epigenetic marks present throughout the genome of a cell (Eichten, Schmitz & Springer 2014). Epigenetic modifications are directed by many different mechanisms…

are finding connections between DNA methylation and its impacts on cognitive aging, as well as neurodegenerative diseases such as Alzheimer's. These same studies are giving reason to believe that environmental factors may be responsible for the epigenetic changes often involved in the progression of neurodegenerative diseases. Some of these factors include diets, nutrients, injuries, physical and cognitive exercise and exposure to chemical agents or heavy metals. This relates to Alzheimer’s,…

identified gene signatures within the in vitro, in vivo and clinical frameworks to further our understanding of the molecular mechanisms of carcinogenesis. More recently, the study of epigenetic changes that occur during carcinogenesis is rapidly deve¬loping into an important research field. For example, epigenetic silencing that occurs through the CpG island methylator…
