Weil is less enthusiastic about white, or button, mushrooms, a species of mushroom that also includes Portobellos and criminis. âButton mushrooms do possess some health benefits, but not the general health benefits found in Asian mushrooms,â Weil says.
What sort of information do they encode, and how can this affect a cell's characteristics and activities? Some genes enable cells to make proteins needed for basic functions; dubbed housekeeping genes, they are active in many types of cells. Other genes, however, are inactive most of the time. Some genes play a role in early development of the embryo and are then shut down forever. Many genes encode proteins that are unique to a particular kind of cell and that give the cell its character - making a brain cell, say, different from a bone cell. A normal cell activates just the genes it needs at the moment and actively suppresses the rest.
They are found in almost every cells nucleus and are made from strands of DNA (deoxyribonucleic acid). Segments of DNA called genes are the ingredients. Each gene adds a specific protein to the recipe.Proteins build, regulate and maintain your body.For instance, they build bones, enable muscles to move, control digestion, and keep your heart beating.n this section, you can investigate what genes are and what they do, and even play a game testing your knowledge of what causes disease.
