How Does Epigenetics Affect The Future

Epigenetics is a study that entails the heritage changes in gene expressions, which includes both the active and the inactive genes; the changes do not involve changes to the underlying DNA sequence. Meaning, it is a change in phenotypes without the differences in genotypes and consequently, affect how the cells read the genes. The epigenetic modification is a natural occurrence but apparently can be influenced by other several factors, including diseases, the environment, and age. Epigenetic changes can result in adverse damages and can end up causing infections such as cancer (Barton et al, 2016). This paper looks at what epigenetics entails, the hidden life of our genes, how food affects genes and how one can elongate life by improving health status.

Burying the dogma of the genomics fixity, epigenetics demonstrates that our lifestyle changes our genes and we pass these mutations on. This discovery opens up new prospects of cure for many diseases. At the level of our genome, there are two kinds of genes: exons which are genes that are expressed and induce the production of certain proteins, and introns which are genes that are eliminated in the transcription of the RNA, and which therefore are not expressed. Environmental conditions could change that by opening introns or closing exons with all possible intermediate situations between these two extremes, from this perspective, epigenetics would correspond to an open or closed switch, to varying degrees. These different positions of switches then open the door to many combinations of genes. This seems to go against a current scientific dogma that considers the genome of a person is inherited from the parents and then remains fixed and determined for his entire life. Moreover, according to the evolutionary theory of Darwin, if mutations occur in a species facing a changing environment, these changes occur only over extremely long periods of time that often number in the thousands or even millions years. Epigenetics shows that on the contrary, these changes are a natural way and very common in nature. With Epigenetics: we can change our

Genetics is a field of science that has long been studied, but researchers and scientists have discovered a new branch that changes the way genetics and evolution has been looked at before. Deepak Chopra and Rudolph E. Tanzi skillfully describe this new subject in their book Super Genes. The book includes information on the history and discoveries of epigenetics, the changes the readers can make to unlock and harness the power of their genes, and the research and experiments that prove the benefits of those changes. Ultimately, the purpose of Super Genes is to inform the readers that they can control their own genes, despite preceding understandings of biological destinies, by making favorable lifestyle choices that leans towards the state of optimum health and well being.

Epigenetics, as a simplified definition, is the study of biological mechanisms that will switch genes on and off.

Researchers first thought the genes you receive from your parents are set in stone since they are made of a genetic code set in our DNA sequence;however, they are discovering that there is a second layer of structure that combines with DNA to decide whether or not a gene is active or not, called the epigenome. The epigenome consists of the DNA, histones, a protein DNA is wrapped around, and chemical tags. The epigenome alters the genetic code by directing signals. The signals come from the environment, which are reacted upon by epigenetic tags to turn a gene either on or off without affecting the DNA sequence. Certain things from our environment that send signals to epigenetic tags to change our genes in the epigenome includes the following:

Before conducting research and watching numerous informational videos on epigenetics, I would have never believed that when my grandmother was my age, she made dietary decisions that have affected me. Technically speaking, epigenetics simply means above genetics. In other words, epigenetics is the traits that you and I inherit, but do not necessarily necessitate the sequence of genes. I took me a while to actually grasp the concept until I thought of it from a musical perspective. Imagine our DNA helix strands as a musical score. There are different music notes as there are genes. If someone were to play Beethoven’s Symphony Number 5 correctly, it would sound the same every time. Basically, if one note is changed, the whole musical piece

The PBS video called “Epigenetics” brought to light some very interesting views. Through rats scientist have been able to see the works of epigenetics and believe that the finding have led to the idea that the change in genetics has the same effect on humans. The most interesting part of the video was that younger pairs of twins have very similar genes, but the older pairs of twin have more epigenetic difference in their genes. This validates the idea that the epigenetic difference in old twins is caused by environmental factors such as lifestyle choices. The idea also alludes to the idea that our parents and grandparents healthy and epigenetics may affect my heath and my children’s health. This leads to the inclination that my child’s health

Do the experiences or events that your parents, grandparents or even great grandparents had in the past affect your genes? Why do some humans have mental health issues and others do not? Behavioral epigenetics examines how nurture shapes nature, where nature refers to biological heredity and nurture refers to everything that occurs during the animal 's lifespan. Epigenetics is the study of alterations in an organism caused by modifications of gene expressions instead of alterations of the genetic code itself. Behavioral epigenetics is the field of study, which analyzes the role epigenetics have in shaping human or animal behavior. Epigenetics works by wrapping DNA around histone octamers to form nucleosomes. Genes will be transcribed or silenced depending on the spacing of nucleosomes, which is determined by complex processes, including post-translational modification of DNA and histones as well as the large numbers of chromatin regulatory proteins recruited to interact with these modifications (Nestler). Behavioral epigenetics explains why humans and animals behave the way they do, not by changing the DNA, but by modification of gene expression rather than alteration of the genetic code, which in turn changes behavior in multiple generations.

Epigenetics is a field where advances are being made daily. Epigenetics is defined as “heritable changes in gene expression that occur without a change in DNA sequence,” as stated by Dr. Alan Wolffe. A way in which we can understand this definition is by taking the analogy of a card game. The cards, the DNA sequence, have been dealt and will not change, however we need to understand how to play the cards, the rules, which is epigenetics. The guidelines can vary and completely change the way the card game is played and who comes out on top. The rules that are studied and understood through this research paper are those of DNA methylation and chromatin. These changes can produce

What is epigenetics? Epigenetics to me is the alteration to our genome that we are able to change in not only ourselves but in our children and future generations as well all based on lifestyle habits we live today. After first watching the PBS video on epigenetics, I was astonished on how our ways of life have such a profound effect upon not only our genes but our future generations of children as well. In the video research was conducted on over forty identical twins ages ranging from three to seventy-four, this was to compare the lifestyle habits such as smoking, exercise, and different diets have on an individual. I found it fascinating that when there was comparing the genomes of the elderly Spanish twins compared to the three-year-olds; we were able to see how much of a difference the Spanish twins genome

For years, scientists believed DNA, deoxyribonucleic acid, was the end-all-be-all: a mould for our cells to be created from. Which does not sound far-fetched since DNA contains all of the information needed for replication, differentiation, growth, and development, in addition to the countless cellular fates, as described in Waddington’s landscape. Instead, DNA is a guide for our cells, and Epigenetics is the tool that coerces them into their final cellular form. The Epigenetics Revolution: How Modern Biology Is Rewriting Our Understanding of Genetics, Disease, and Inheritance written by Nessa Carey, outlines the process of DNA versus Epigenetics, and the developments they have had within the scientific field. This paper will examine the fundamental distinction constructed by Nessa Carey between DNA as a script versus a template. This analogy of DNA as a script.

It is often thought that our DNA is a concert blue print and the way we personally engage with the environment has no effect on our future generation. However through experiments and recent studies, scientists have discovered external environmental factors can effect ones DNA sequence. It was found that genes have the ability to switch on and off and affect how cells read genes. This new avenue is called Epigenetics. Epigenetics is the study of heritable changes in gene expression. It describes the outward phenotypic appearance that is not the result to changes in the DNA sequence but instead, changes to the chemical tags that overlay the genome. Epigenetics is often described as the missing link between the environment an individual is exposed

Epigenetics are stable heritable traits that cannot be explained by the changes in DNA. The term also refer to the changes themselves. The term epigenetic is also used in developmental psychology to describe psychological development as a result of ongoing exchange between heredity and the environment. Epigenetics is broadly defined as those changes which are not dependent in the genome sequence. It is a method of controlling the genome without involving the alteration of the genomic sequence itself. Epigenetics, in simple words, is the evolution and passing on of genes.

The different events and social behaviors that different animals were exposed to in infancy effected their physiology and behavior and those effects were far reaching and long lasting, following them for the rest of their lives. Experiences and environmental factors cause epigenetic changes to genes, but the influence is even further reaching that that. Epigenetic influences even occur in utero, the mother passes on more than her genetic material. The fetus’s epigenetics are influenced by the experiences of the mother during pregnancy, things like the mother’s diet and stress levels can influence her offspring later in life. We are all born into different circumstances and situations. Location and socioeconomic status vary greatly among the human population. The influence that epigenetic factors have on how our genes are expressed can be helpful to aide in how we navigate our own lives in relation to the specific set of circumstances we are born into. The way our genes are influenced by out mother (during pregnancy) can aid us in adapting to the specific “world” we are born

Epigenetics can be hereditable or environmental factors that affect the expression of genes and lead to changes in gene expression. Unlike genetics, epigenetics does not only have to do with which genes are passed down to the offspring and the DNA sequence. The environmental conditions of the offspring’s parents impact the genes in their eggs and sperms by “switching on” certain genes and “switching of” others (Dowshen). Since the genes expression of the gametes are affect, the phenotypes of the offspring will change. Even in a person’s lifetime, environmental factors such as stress, chemical exposure, and diet can continue to impact gene expression through DNA methylation. During DNA methylation, a methyl group is randomly added to a 5-carbon cytosine ring, making 5-methylcytosine and these groups inhibit transcription. (Cheriyedath). Due the fact that transcription is not possible, the expressing of the genes in that section of the DNA strand will be suppressed. The attachment of the methyl group to DNA is not determined, which means that
