Which two types of organic polymers are made from the same type of monomer?

DNA and RNA

Explanation:

Nucleotides serve as the blueprint for DNA transcription, translation and protein synthesis. Nucleotides are the monomers of linear polymer nucleic acids such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which carry the genetic information of an organism. Nucleotide monomers are made of a five-carbon sugar, a phosphate and nitrogenous bases. The bases include adenine and guanine, which are derived from purine; and cytosine and thymine (for DNA) or uracil (for RNA), derived from pyrimidine. A phosphodiester bond connects the sugars of nucleic acids together.
