Answer:
1. Nucleotides
2. Amino acids
3. Monosaccharides
Step-by-step explanation:
There are four major biological polymers in nature namely: carbohydrate (polysaccharides), lipids, proteins and nucleic acids. These polymers are formed from smaller units called MONOMERS, which are linked together via chemical bonds. The monomeric units of the polymers are listed below:
- Carbohydrates or polysaccharides are polymers of monomers called MONOSACCHARIDES linked by glycosidic bonds.
- Nucleic acids are polymers of monomers called NUCLEOTIDES linked by phosphodiester bonds.
- Proteins are polymers of monomers called AMINO ACIDS linked by peptide bonds.
