environmental exposure can shape the way in which epigenetics emerge (Healy). Though Ngun’s work does not provide knowledge of the exact time at which these genomes tend to activate, his research does show that environmental influences may be a powerful determinant in predicting sexual orientation later in life. University of Maryland pharmacology professor Margaret M. McCarthy concurs with Ngun’s research, claiming that regardless of how strongly epigenetic factors affect the presence of…

The developments of cancer in children have had many disagreements between scientist and researchers. Some might agree that it hard to determine what causes cancer in children. Scientist around the world has developed their own theories on the development of cancer in children. Although there are disagreements, many of the scientists have come to the conclusion that some forms of cancer have been the linked to genetic cells that are formed through fertilization of the embryo, which could be…

Epigenetics “refers to external modifications to DNA that turn genes "on" or "off." These modifications do not change the DNA sequence, but instead, they affect how cells "read" genes.” () Gene expression can be affected by the environment and the life style…

rates of disease, but this is not the case. Blacks in the Caribbean also express lower rates of hypertension. The continuation of the biological argument, then relates to epigenetics, which is the phenomenon genetic code in response to external circumstances, particularly in regards to trauma. Looking at the issue with an epigenetic lens, experiencing racial trauma and macroaggressions on a daily basis could change the genetic code to be more susceptible to disease. This theory is supported…

Epigenetic Inheritance Of Traumatic Events In the excerpt “Hiroshima and The Inheritance of Trauma” the author, Sarah Stillman, discusses the psychological effects of traumatizing events and how it can spread like a contagious disease. Stillman references the traumatic bombing of Hiroshima and how the detrimental trauma has affected the mother, Shoji, and the next generation, her daughter Minori. The relationship between Shoji’s experience of the bombing being translating to Minori is a valid…

Theories were proposed related to epigenetics and how external environmental triggers could cause certain genes to be duplicated, changed, or shut off entirely to give the next generation a survival advantage. Recently, scientists have discovered how those external factors related to epigenetics can affect fetuses, through experiments where it was supported that pregnant mothers who experienced famine during pregnancy…

Prokaryotes, specifically bacteria, have feedback regulatory mechanisms like eukaryotes do to make tryptophan. Tryptophan is one of the 20 amino acids which we all need. If there is a lot of tryptophan made, then you turn off the enzymes that are involved in tryptophan synthesis by binding and causing a change in shape of the enzyme (negative feedback). In addition, repressors are proteins that bind to the operator and prevents expression of the gene. However, the repressor is unable to bind to…

that epigenetics can allow a grandmother to influence her grandchild’s DNA because we know that environmental factors and factors from the mother come into play when the baby is developing inside the mother. But for females, they are born with a full set of eggs that she will have for life. So, that means that the eggs the grandchild developed from were created in its mother’s ovaries when the mother was still in her mother’s womb. This means that when the grandmother was passing epigenetic…

Introduction Eugenics has become somewhat of a buzzword in mainstream discussions of the topic. As with most buzzwords, it is overused to the point of overshadowing broader applications of the topic (For an example see Peter Singer on Animal Rights pp. 196-203). Notwithstanding, this paper will discuss heavily the topic of Eugenics, and more specifically Julian Savulescu’s stand on Eugenics and whether he believes in endorsing a program of eugenics. Savulescu’s opinion will be analyzed mostly by…
