Question 2

Correct Answer:

Verified

DNA is double stranded; contains the sugar deoxyribose; possesses cytosine, guanine, adenine, and thymine; and is restricted to the nucleus. RNA is single stranded; contains a ribose sugar; possesses cytosine, guanine, adenine, and uracil (instead of thymine); and functions in protein synthesis in the cytoplasm. Both nucleic acids are composed of nucleotides and function in gene expression.
