Which of the following is true of the differences between DNA and RNA?
|A||DNA contains a five-carbon sugar, while RNA contains a six-carbon sugar.|
|B||DNA contains phosphate groups, while RNA does not.|
|C||RNA contains the purine base adenine in place of the purine base guanine contained in DNA.|
|D||RNA contains a different five-carbon sugar than DNA.|
One of the major differences between DNA and RNA is that RNA contains the five-carbon sugar ribose, while DNA contains the five-carbon sugar deoxyribose. Both DNA and RNA contain phosphate groups, and both contain adenine and guanine. (RNA contains the pyrimidine base uracil instead of the pyrimidine base thymine.)
