In genetics, DNA and RNA are classified as which type of biomolecule?
A
Steroid lipids
B
Triglycerides
C
Polysaccharides
D
Nucleic acids
Verified step by step guidance1
Understand that biomolecules are large molecules necessary for life, and they are classified into categories such as lipids, carbohydrates, proteins, and nucleic acids.
Recall that DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are molecules that store and transmit genetic information in cells.
Recognize that DNA and RNA are composed of nucleotide monomers, which consist of a sugar, a phosphate group, and a nitrogenous base.
Identify that molecules made up of nucleotides are classified as nucleic acids, distinguishing them from lipids (like steroid lipids and triglycerides) and polysaccharides (complex carbohydrates).
Conclude that since DNA and RNA fit the description of nucleotide polymers, they belong to the biomolecule category called nucleic acids.
