Question

nucleic acids. nucleotides are the building blocks of nucleic acids, consisting of three components: a five - carbon sugar (deoxyribose in dna and ribose in rna), a phosphate group, and a nitrogenous base. the arrangement of these components within nucleotides plays a crucial role in the overall structure and function of dna and rna. in dna, the sugar - phosphate backbone forms the framework of the double helix, while the nitrogenous bases project inward, forming complementary base pairs (a - t and c - g) that stabilize the helical structure. in rna, the single - stranded nature allows for diverse folding patterns, and base pairing occurs between complementary bases (a - u and c - g), enabling the formation of intricate secondary and tertiary structures that are essential for its various functions. choose the correct answer. what nitrogenous bases pairs with adenine (a) in rna? cytosine (c) guanine (g) uracil (u)

Explanation:

In RNA, adenine (A) pairs with uracil (U) through hydrogen - bonding. This is different from DNA where adenine pairs with thymine (T).

Answer:

uracil (U)
