So having high blood sugar doesnât mean that you ate a lot of table sugar and the sugar is now in your bloodstream; it means you ate a lot of carbohydrates (from any source) and the sugar (glucose) is now in your bloodstream. Any digestible carbohydrate can raise blood sugar, although some raise it higher and faster than others.
If a mutation alters junk DNA, it doesnât do any harm because the junk isnât doing us any good to begin with. If our genome was 80 percent functionalâthe figure batted around when the ENCODE project results first came outâthen we should be extinct.
Only recently have biologists begun to entertain the possibility that this so-called junk DNA might not be junk after all. In fact, scientists now believe that TEs make up more than 40% of the human genome (Smit, 1999).a Aa Aa. Transposable elements (TEs), also known as jumping genes  or transposons, are sequences of DNA that move (or jump) from one location in the genome to another.
