Your journey through life began when your mother's egg was fertilized by your father's sperm. Both egg and sperm carried coded messages from your parents' families and ancestral relatives, conveyed via genes through the generations. It was through the interaction of genes that all of your cells and organs were structured and now function. The miraculous complexity of our bodies may at first seem difficult to fathom, especially since one cannot see a gene. However, our inability to visualize a gene need not prevent us from understanding critically important information about genes.
Our genes regulate, modify, control, promote, enhance, and otherwise influence every aspect of our body's structure and functioning. Whether you are tall or short, fat or thin, fair- or dark-skinned, have certain facial characteristics, are allergic, or are affected by a genetic disorder is purely a function of your genes. Your genes largely determine your body's characteristics, your various susceptibilities or resistance to all diseases, how you react to medications, and whether you will transmit certain genetic disorders or fall victim to one or more of them. However, even though all aspects of health depend upon your genes, their interaction with the environment is especially important. In fact, responses to environmental dangers have in an evolutionary way resulted in genetic adaptations for survival.
Exercise play very important role in gene expression. The activity of structural genes in determining the amount of a gene product. These are the so-called control genes. These controllers are in turn regulated by more distantly located genes (called regulator genes), which in turn produce a protein that turns a gene on and off (called a repressor).
The gene is unquestionably the leader; but it is always surrounded and aided by an entourage. Certain letters (bases) in the DNA chain that abut the sequence of letters that constitute the gene, make up the promoter..............
