Detailed explanation-1: -The statement that shows a monomer that is correctly matched with its polymer is “An amino acid is a monomer of proteins.”
Detailed explanation-2: -DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
Detailed explanation-3: -In case of nucleic acids, monomers are the nucleotides composed of nitrogenous base, pentose sugar, and phosphate group whereas DNA and RNA are considered as polymer of nucleic acids. DNA and RNA are composed of monomers termed as nucleotides.
Detailed explanation-4: -Monomers are atoms or small molecules that bond together to form more complex structures such as polymers. There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides.
