Epigenetics: molecular mechanisms and implications for disease
WebAging is an inevitable outcome of life, characterized by a progressive decline in tissue and organ function. At a molecular level, it is marked by the gradual alterations of biomolecules. Indeed, important changes are observed on the DNA, as well as at a protein level, that are influenced by both genetic and environmental parameters. These molecular changes … Epigenetic changes can affect your health in different ways: Infections Germs can change your epigenetics to weaken your immune system. This helps the germ survive. Example: Mycobacterium tuberculosis Mycobacterium tuberculosis causes tuberculosis. See more DNA methylation works by adding a chemical group to DNA. Typically, this group is added to specific places on the DNA, where it blocks the proteins that attach to DNA to “read” the gene. This chemical group can … See more DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access … See more Your DNA is used as instructions for making coding and non-coding RNA. Coding RNA is used to make proteins. Non-coding RNA … See more family guy quest for stuff cheats iphone
