WebAug 15, 2024 · Epigenetics remains the study away how your behaviors and environment can cause alterations that affect and way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change thine DNA sequence, but they can modify how their body reads a DNA sequence. WebHow Genes Work. What are proteins and what do they do? How do genes direct the production of proteins? Can genes be turned on and off in cells? What is epigenetics? How do cells divide? How do genes control the growth and division of cells? 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 be removed through a process called demethylation. Typically, methylation turns genes “off” and … See more DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access the DNA as easily, so the gene is turned “off.” When histones are loosely packed, more … See more Your DNA is used as instructions for making coding and non-coding RNA.
