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.
RNA Polymerases, RNA-Dependent (Molecular Biology) In all organisms the major flow of genetic information is from DNA to RNA using DNA-dependent RNA polymerases, with the DNA itself being replicated by DNA-dependent DNA polymerases. Some of the DNA synthesis, primarily of specific viruses (retroviruses) and retroelements, is from RNA by reverse transcriptase. However, there are many viruses of both prokaryotes and eukaryotes that have RNA genomes and that replicate by the synthesis of RNA from the genome.
