Nucleic acids, proteins, and other large biological molecules are known as polymers because

Please read the explanation section.

Explanation:

They are called polymers because they contain many small, repeating sub-units bonded together.

In the chemical and biological science, some small molecules make a polymer, which is a molecule. A polymer is that kind of molecule, which is the result of binding up between smaller molecules called monomers.

A monomer is a type of polymer that is resulting from the assembly of many small units that are similar in nature. A monomer has a chemical compound with repetitive structural units. A polymer is a molecule made up of a chain of similar molecules, called

E.g., DNA, glycogen, amino acid, and proteins are polymers
