Compléter Epigenetics (D)Version en ligne Fill in the gaps. par Boglárka Kozári 1 reversible connection environment alter result turn reads expression instructions affect sequence Your genes play an important role in your health , but so do your behaviours and , such as what you eat and how physically active you are . Epigenetics is the study of how your behaviours and environment can cause changes that the way your genes work . Unlike genetic changes , epigenetic changes are and do not change your DNA , but they can change how your body a DNA sequence . Gene refers to how often or when proteins are created from the within your genes . While genetic changes can which protein is made , epigenetic changes affect gene expression to genes " on " and " off . " Since your environment and behaviours , such as diet and exercise , can in epigenetic changes , it is easy to see the between your genes and your behaviours and environment . 2 survive information aids damage proteins determine turned regulation scars response develop age indelible likely weaken identified risk detect Likewise fade suggests Your epigenetics change as you , both as part of normal development and aging and in to your behaviours and environment . Epigenetic changes begin before you are born . All your cells have the same genes but look and act differently . As you grow and develop , epigenetics helps which function a cell will have , for example , whether it will become a heart cell , nerve cell , or skin cell . For example , your muscle cells and nerve cells have the same DNA but work differently . A nerve cell transports to other cells in your body . A muscle cell has a structure that in your body ? s ability to move . Epigenetics allows the muscle cell to turn " on " genes to make important for its job and turn " off " genes important for a nerve cell ? s job . Current work that so - called epigenetic mechanisms of gene could explain how early life experiences can leave chemical marks on the brain and influence both physical and mental health later in life . Around 60 years after the Dutch Hunger Winter Famine ( 1944 - 1945 ) , researchers looked at people whose mothers were pregnant with them during that time . It out that they were more to develop certain diseases such as heart disease , schizophrenia , and type 2 diabetes . Epigenetic changes can affect your health in different other ways . For example , germs can change your epigenetics to your immune system . This helps the germ . Certain mutations make you more likely to cancer . , some epigenetic changes increase your cancer . Epigenetics can be used to help determine which type of cancer a person has or can help to find hard to cancers earlier . Not all epigenetic changes seem permanent . Most changes to DNA after five years if people quit smoking , for example , but some changes last decades . Some genes had not been as being affected before . Smoking DNA in clear patterns . Most of the fades over time , but not all of it .
