Epigenetic Influences

Genetics can play a role in obesity. “Offspring of obese parents are much more likely to become obese than offspring of lean parents”, according to what Kris Gunnars wrote on https://www.healthline.com. Even though our future cannot be determined by our genes, genes can have a major

Obesity has been linked to genetics. It has been researched and proven that children with parents who are obese, would have between 5-25% chance of likely inheriting genes that would eventually make them obese. However, genes is not an excuse for obesity because it does not work alone but must have the right factors present to manifest.

First of all, there have been many researches to show that genetics can be linked to obesity. Obesity depends on the person's genetic make-up. Our genes regulate how your body stores, captures and release energy from food. According to research, obesity runs in families. Obesity and even how thin you are depends on your families’ history. “In a study of adults who were adopted as children, researchers found that participating adult

Epigenetics is the study of cellular and physiological traits that are not caused by changes in the DNA sequence but they are triggered by chemical reactions that activate and deactivate parts of the genome and in specific locations. Therefore, epigenetics is the study of chemical reactions and factors that influence them. Hypothetically, epigenetics has the huge potential in terms of the uncovering genetic development of organisms, including humans, and the impact of chemical reactions that occur under the impact of various factors and affect genome activation and deactivation in specific locations. In this regard, further studies and development of epigenetics is essential but the impact and role of epigenetics should not be overestimated

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

A person is more likely to develop obesity if one or both parents are overweight. Numerous people are obese because of their family history. The reason why genetics can contribute to the obesity issue is because they can change and affect hormones that control the fat cells. “For example, one genetic cause of obesity is Leptin deficiency. Leptin is a hormone produced in fat cells and also in the placenta. Leptin controls weight by signaling the brain to eat less when body fat stores are too high. If, for some reason, the body cannot produce enough leptin or leptin cannot signal the brain to eat less, this control is lost, and obesity occurs” (R.

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

If one biological parent is obese, the child has a 50% chance of being obese, but if it so happens that both parents are obese, the chances of obesity in their offspring will increase to 80%. There are some medical issues that cause obesity, and only 1% of obesity is caused by a lack of physical activity.

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

The development and importance of epigenetics has revealed to the world the explanation of many gene expressing mutations also factors that may account for genetic variation. The result of this observation helped many scientists around the world cures as well as new analysis methods to help survivors .The understanding obtained from the discovery of epigenetics has and will continue to inform ways of preventing and manipulating genetic expressions to our advantage throughout these upcoming generations. Throughout this essay response, the following information will cover the focus on how epigenetics can account for genetic variability in organisms, it will also relate to factors

All cells in the body contain the same DNA sequence. Although all cells contain an identical DNA sequence, they all have different cell structures and functions. Each structure and function of the cell differs because the cell has specific use for or will only express certain genes. Genes in DNA are expressed when they are read and transcribed into RNA which then gets translated into proteins by ribosome structures. Proteins are used to determine a cells characteristics and functions. Inside of each cell the DNA as well as histones can be tagged by tiny chemicals that modify gene expression. These chemical tags have the responsibility that causes genes to be turned on or turned off. This causes genes to be expressed or silenced. The epigenome is a wrapped up package of DNA.

Noted by the Research Chair in Obesity from Université Laval (n.d.), “obesity risk is two to eight times higher for a person with a family history as opposed to a person with no family history of obesity, and an even higher risk is observed in cases of severe obesity.” (Université Laval, n.d., n.p.) It is not only genetics though as you can see in the previous paragraphs. If someone is brought up eating unhealthy and exercising less, this chain pattern will continue and the main cause to this would be our parents. The way that you and your family eat now is more than likely the way the generation before ate because it's what they grew up eating and continued to eat when they became an

To me epigenetics is the how behind each and every person’s personality. We always look for answers to questions, that are right now to incomprehensible to us but still trying to quantify them, and epigenetics is the latest answer. First we were looking at the gnome to try and answer medical questions of who and why certain people get diseases, now with that not giving us the results we want we are digging deeper into the bodies makeup trying to uncover its secrets.

Epigenetics is defined as the study of heritable regulation of gene activity that is not determined by the genetic sequence. Our genes are the combination of four bases or parts labeled A, C, G and T, which when disrupted the call mutations. Today we know that genes are controlled by other mechanisms, for example by adding a chemical group called methyl DNA chain or adding another chemical group called acetyl histone proteins, the “keys” of our genome. Remember that genes are DNA fragments are expressed resulting RNA then produce a protein: almost everything we touch in our body are proteins, melanin in our skin, our blood hemoglobin, etc. Rigorous control genes must exist: we do not want a cell of the eye expresses a protein characteristic

It’s been shown that children with obese parents are more likely to become obese. Heredity contributes between 5-25 percent risks of obesity. Other risks can be attributed to the environment and behavior. Obesity is generally linked to over eaten but in most cases its heredity problem children should be careful because genes can also pass to their offspring. The problem cannot be corrected but you can prevent it. Children should be given an appropriate diet and should be deterred from overeating. Child obesity can be predicted at an early stage and children should be aware of the consequences of obesity.
