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.
Best Answer: Most mutations are harmful, and most organisms that get these mutations are never even born (hatched or sprouted). If an organism with a harmful mutation does survive, it usually doesn't do as well as its normal relatives. For example, in humans, Downs' Syndrome is a mutation where the person gets an extra chromosome #23.
