the monomer below is composed of a pentose sugar called ribose, a nitrogenous base called uracil and a phosphate group. this monomer is an integral part of the following macromolecules? carbohydrate dna phospholipid rna

The correct answer is RNA.

RNA or ribonucleic acid is a polymeric molecule important in many biological functions in decoding, coding, expression of genes, and regulation. RNA and DNA are nucleic acids, and along with proteins, lipids, and carbohydrates, forms the four prime macromolecules important for all the known forms of life.

Each nucleotide in RNA comprises a ribose sugar, with carbons numbered 1 prime through 5 prime. A base is connected with the 1 prime position, usually, adenine, guanine, cytosine, or uracil. A phosphate group is combined with the 3 prime position of one ribose and the 5 prime position of the next.
