Step 1: Understand the basic definitions of DNA and RNA. Both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are nucleic acids, which are biological macromolecules essential for life.
Step 2: Recognize that a molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Step 3: Recall that both DNA and RNA consist of long chains of nucleotides, which are molecules made up of a sugar, a phosphate group, and a nitrogenous base.
Step 4: Since DNA and RNA are composed of these nucleotide molecules linked together, both DNA and RNA themselves are considered molecules.
Step 5: Therefore, the correct statement is that both DNA and RNA are molecules, as they fit the definition of molecules in chemistry and biology.
