Question

Which of the following is true about the differences between the types of nucleic acids? A. RNA is typically a double-stranded molecule, whereas DNA is always single stranded. B. DNA contains the five-carbon sugar deoxyribose, whereas RNA contains the five-carbon sugar ribose. C. DNA can contain the nitrogenous base uracil, whereas RNA can contain the nitrogenous base thymine. D. RNA contains genetic information, whereas DNA is involved in the direct production of proteins.

Answer 1

Your correct answer is B.

Here's why:

DNA is made of deoxyribose, phosphates, and your nitrogen bases (adenine, thymine, guanine, and cytosine.)
DNA is double stranded.

RNA is made out of ribose, phosphates, and nitrogen bases (adenine, uracil, guanine, and cytosine.)
RNA is single stranded.

RNA is transcribed DNA that travels out of the nucleus, where it is made, and travels down into the ribosome where proteins will be made for the body's well being.
