Question Detail
Question
DNA and RNA are similar in that both: a. are in the form of a double-helix b. contain nitrogenous bases c. are double-stranded molecules d. contain the same sugar
Correct Answer
Option B is the correct answer.
Detailed Explanation
Both DNA and RNA are nucleic acids and contain nitrogenous bases (A, G, C, with T in DNA and U in RNA). DNA is usually double-stranded and forms a double helix; RNA is usually single-stranded. DNA has deoxyribose sugar; RNA has ribose sugar.
Hint
They both have the 'letters' A, G, C, but not all the same ones.
