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.
DNA screening is done to test your DNA for these harmful genes so that if you are a carrier of a certain gene the doctor can give you medication to prevent it from getting worse (think HIV and AIDS), or from passing it on to your children. hope this helps!
