which are long chains formed by the process of polymerization?\nsubunits\nethylenes\nmonomers\ndna strands

Brief Explanations:

Polymerization is the process of combining monomers to form long - chain polymers. Monomers are the building blocks that link together to create these long chains. Subunits can refer to various parts in different contexts but not specifically the long chains formed by polymerization. Ethylenes are a type of monomer but not the general term for long chains formed by polymerization. DNA strands are a specific type of polymer but not the most general answer for long chains formed by polymerization.

Answer:

monomers
