Guida verificata passo dopo passo1
Understand that DNA is a polymer made up of repeating units called nucleotides.
Recall that each nucleotide consists of three components: a phosphate group, a sugar (specifically deoxyribose in DNA), and a nitrogenous base.
Recognize that monosaccharides joined by glycosidic bonds refer to carbohydrates, not DNA.
Know that amino acids linked by peptide bonds form proteins, which are different from DNA.
Identify that fatty acids and glycerol molecules make up lipids, which are also distinct from DNA.
