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.
Mutations are random changes in DNA. Most DNA does not actually come into play in building the organism's body so mutations in that DNA are neither helpful nor harmful. Mutations in the DNA that is used to build the organism's body are mostly harmful.utation is a change in the encoded hereditary information in living things and viruses. Whether or not it's good or bad depends on what the effects of it are. And even that is relative. Example: A plant grows with a new mutation, the ability to produce a more powerful toxin in it's seed pods.
