Epigenetics

Epigenetics refers to covalent modification of DNA, protein, or RNA, resulting in changes to the function and/or regulation of these molecules, without altering their primary sequences. Epigenetics has helped the field of genetics it allows scientist to alter the way genes are read and to tell if the gene is active or inactive. Epigenetics can be used for many great causes, such as preventing leukemia or stop aging in adults. The preventing of leukemia is done by the the scientist finding the…

exceptions. Epigenetic refers to the external modification that turns genes “on” or “off” to DNA. These modifications in DNA sequence don’t change, but can affect the “read” of genes [1]. One example is epigenetics in lung cancer. It is critical for the initiation and progression of the lung cancer affecting all major cell regulatory pathways. Another example is epigenetic changes that are passed down to future generations if changes occur in sperm and egg cells. Cells make epigenetic changes…

Epigenetics is the modification of the genome to regulate gene expression. This process is achieved through a variety of different mechanisms including but not limited to, chromatin condensation, acetylation modification, and methylation modification. Gene expression can also be altered through a number of non-epigenetic mechanisms, such as environmental factors, like temperature, and the introduction of endocrine disrupting chemicals (EDC) into the environment. The level of chromatin…

organization and epigenetic changes in DNA methylation and histone modifications. Numerous genetic mutations of inherited cancers have been identified, as there is a large body of research dedicated to identifying DNA mutations that are linked to tumor initiation. After initiation, tumor progression often occurs due to multiple additional dysregulation events, including epigenetic changes which are often not as easily identifiable as DNA mutations (Feinberg et al. 2004). Although epigenetic…

Simone Francis Reference number: 2167-6527 Epigenetics is the study of modifications to the genes of organisms. The way in which our genes behave can be altered by our epigenomes without changing our DNA sequence. They can be altered by different factors of our environment such as what we eat, drink, etc. The video on epigenetics was very informative. Prior to watching the video, I had no knowledge of what epigenetics was nor have I ever heard about it. I thought the experiments in the lab on…

Influences of Epigenetics on Cancer Introduction Cancer before epigenetics History of cancer. Cancer is characterized by an out of control growth of tissues within one’s body. These cells are known as a mutated tissue cells, and these resulted in a new replication patterns. The word cancer was derived from the term carinas and carcinoma to describe non-ulcer forming or ulcer-forming tumors by the Greek physician Hippocrates (460-370 B.C). Studies over the centuries have been trying to determine…

Epigenetics: The Influence of Environment Epigenetics is the study of changes in the gene expression of organisms. Epigenetic changes assist in normal cell differentiation, determining which genes of an organism will be turned either ‘on’ or ‘off’ during development (Masterpasqua, 2009). These changes to the epigenome can be linked to many different factors- recent research indicates that variations can be linked to intrinsic factors such as the genotype, or genes of the organism, or, arguably…

Epigenetics, a contemporary and often misunderstood topic in the field of biology, was first defined in the early 1940s as “the branch of biology which studies the causal interactions between genes and their products with bring the phenotype into being” (Dupont 2009). Since then, as understanding of the human genome has developed and grown, a complex array of errors and dysfunctions in the processes of gene regulation, expression, and replication have been shown to cause, or correlate strongly…

I believe epigenetic marks are inherited and not completely erased. Research has shown that many epigenetic marks remain, and genetic information is passed from one generation to the next, this process is called epigenetic inheritance. The science of epigenetic inheritance goes against conventional wisdom that “that inheritance happens only through the DNA code that passes from parent to offspring” (Epigenetics and Inheritance, 2016). Basically, it means that the historical experiences from…

Epigenetics. While it has been shown that the inheritance of specific genes can cause eating disorders, the reverse is also true. According to a Canadian study, the onset of eating disorders such as bulimia, especially when they are long term, can actually cause changes in the very expression of one’s genes. These changes can be passed down to progeny and increase their likelihood of developing an eating disorder as well. This phenomenon is known as epigenetics, and its biological mechanisms…
