Final answer:
The statement is true; RNA is similar to DNA as both are nucleic acids composed of nucleotides featuring a nitrogenous base, a five-carbon sugar, and a phosphate group.
Step-by-step explanation:
The statement that RNA is like DNA in that it is a nucleic acid, a large biomolecule composed of carbon, phosphate, and nitrogen is true. Both RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are nucleic acids made up of long chains of nucleotides, where each nucleotide is composed of a nitrogenous base, a five-carbon sugar (ribose in RNA and deoxyribose in DNA), and a phosphate group. The five-carbon sugar present in RNA is ribose, which has a hydroxyl group at the 2' carbon, differentiating it from the deoxyribose sugar in DNA. RNA and DNA play crucial roles in genetic information transfer and protein synthesis, although RNA is generally single-stranded and DNA is double-stranded.
