1. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. 2. RNA is a single-stranded nucleic acid. 3. RNA nucleotides have a uracil base instead of thymine.
Structurally, DNA and RNA<span> are nearly identical. As mentioned earlier, however, there are three fundamental </span>differences<span> that account for the very different functions of the two molecules. </span>RNA<span> has a ribose sugar instead of a deoxyribose sugar like </span>DNA.RNA<span> nucleotides have a uracil base instead of thymine.</span>
One thing that a scientist might ask about the movement of carbon dioxide through the whale and its surrounding is “how did the whale get the carbon dioxide?”. Another thing that a scientistmay ask about this is “how does the carbon dioxide affect the ecosystem?”
