In the context of DNA structure, what type of biomolecule are DNA and RNA?
A
Nucleic acids
B
Triacylglycerols (lipids)
C

D
Polysaccharides (carbohydrates)
Verified step by step guidance1
Understand that biomolecules are large molecules necessary for life, including proteins, lipids, carbohydrates, and nucleic acids.
Recall that DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are molecules that store and transmit genetic information.
Recognize that molecules involved in genetic information storage and transmission belong to the class called nucleic acids.
Differentiate nucleic acids from other biomolecules: triacylglycerols are lipids used for energy storage, proteins perform various functions including enzymes, and polysaccharides are carbohydrates used for energy and structure.
Conclude that DNA and RNA are classified as nucleic acids because of their role and chemical structure.
