Guida verificata passo dopo passo1
Understand that DNA and RNA are nucleic acids, which are polymers made up of repeating units called monomers.
Identify the monomers of nucleic acids: these are nucleotides, which consist of three components—a phosphate group, a five-carbon sugar (deoxyribose in DNA and ribose in RNA), and a nitrogenous base.
Recognize that fatty acids are the building blocks of lipids, not nucleic acids.
Recall that amino acids are the monomers of proteins, not nucleic acids.
Note that monosaccharides are simple sugars and serve as monomers for carbohydrates, not nucleic acids.
