Although each cell in your body contains the same set of genes, the genes that are “turned on” differ depending on the type of cell. What signals different genes to be “turned on” or transcribed in different cells? What types of behaviours or environmental circumstances can lead to changes in an individual’s epigenome? Explain. 3. Explain how changes in your epigenome can alter the DNA of your future children before they are even born. 4.) Explain TWO implications of these findings for society. (Hint: think big! Implications for how disease is transmitted, intergenerational trauma, the cycle of poverty, etc.)
From the list of answers below (A-D) select the correct answer(s). There may be more than one correct answer. B. Identical twins have the same genome, as well as the same epigenome. C. Epigenetic changes can be introduced or changed by social experience. D. Epigenetic changes are permanent and once acquired can never be changed. A. Identical twins have the same genome, but may have different epigenomes.
"Tobacco smoking triggers a large number of somaticmutations and epigenetic changes". Define about this ?
Often, the physical characteristics of genetically identical twins become increasingly different as they age, even at the molecular level. Explain why this is so from the point of view of epigenetics.
The introduction to this chapter describes the long-term effects of famine on people conceived during the Dutch Hunger Winter. a. What evidence suggests that these are epigenetic effects? b. What additional evidence would help to demonstrate that these changes are due to epigenetic changes?
Please explain how the deletion of the same set of genes can result in such different diseases. The example for this question being Prader-willi syndrom and Angelman syndrome. In your answer, be sure to discuss the role of genetic imprinting and epigenetics.
Epigenetics has been described as “inheritance, but not as we know it.” Do you think this is a good definition? Why or why not?
What are epigenetic modifications? a. the addition of reversible changes to histone proteins and DNA b. the removal of nucleosomes from the DNA c. the addition of more nucleosomes to the DNA d. mutation of the DNA sequence
1. Does the epigenome change? What can effect changes to the epigenome?2. Can epigenetics end the nature vs. nurture debate? Why or why not?3. Can we manipulate epigenetic marks? Expound on your answer.
http://www.letsgethealthy.org/students/games/epigenetics-game/ (Links to an external site.) For the assignment this week I want you to play this epigenetic game that will show you how your choices (which will be the equivalent of of external factors in someone life) make your genes act differently. Last week, we learned about biology and race and how these fit together in the formation of biological determinants and social misconceptions. For this week's discussion, play the game. Discuss with your classmates what happened, and what you have learned about epigenetics and how this changes your understanding of genetics . How do epigenetic changes and epigenetic mechanisms in general influence health, our concepts of race, and inequality?
stion 20 of 20 CO Epigenetics is the study of heritable traits that are not induced by changes to DNA sequence. Epigenetic changes can be inherited during somatic cell division to regulate the daughter cells of an individual organism. Most epigenetic modifications are reset prior to meiosis. However, some epigenetic changes can be inherited across generations. For example, environmental factors such as nutrition and chemical exposure can induce heritable epigenetic changes in animal models (Relton and Davey Smith, 2012). Genome imprinting is one type of epigenetic modification in which a cell or organism can reduce the expression of a gene and thereby silence the gene. Genome imprinting is caused by DNA methylation and histone modification, which reduce expression of a gene. The silencing occurs in a parent-of-origin-specific manner, where either the maternally derived allele or the paternally derived allele is imprinted and silenced. Expression occurs only through the nonimprinted…
