How do the bases thymine and uracil differ?

Question

Accepted Answer

Hello everyone. Today, we have the following problem which of the following accurately identifies the difference in the primary structures of RN A and DNA. So in just drawing out the sugar or ribose sugars of DNA and RN A, we will start with DNA, which is a pintos sugar with the following configuration. So we would have our nitrogenous base. And then on carbons two, on carbon two, we simply have two hydrogens. And on carbon three, we have one hydroxyl group. And this will come into play when comparing the difference is between DNA and RN A. So we have the phosphate group on carbon five of that deoxy ribose sugar. In drawing the sugar for RN A, we also have a Pintos sugar. We have our nitrogenous base that is on carbon one. But the difference is that on carbons at two and three, we have two hydroxyl groups. Carbon five will have the phosphate group on carbon five and the other phosphate for DNA should have the corrected formula. So let's analyze each statement statement. A says that DNA contains OL while RN A contains thymine. Well, this is incorrect as DNA contains thymine. Whereas RN A contains IL B states that RN A contains a rival sugar while DNA contains a deoxy rival sugar. And we just illustrated that making B the correct answer choice C is incorrect. As both DNA and RN A are made of nucleotides, neither are made of amino acids. And D states that RN A contains a hex or sugar while DNA contains a pin of sugar. Well, this is incorrect as both DNA and RN A contain a pinto sugar. And with that, we have solved the problem overall, I hope this helped and until next time.
