What scientific knowledge about macromolecules is a direct result of gerardus johnannes mulder’s 1838 discovery? all proteins contain carbon, hydrogen, oxygen, and nitrogen. all carbohydrates contain carbon, hydrogen, and oxygen. nucleic acids are polymers with nucleotide monomers. the helical structure of dna is essential for protein production. these are the answer choices

The correct answer will be-all proteins contain carbon, hydrogen, oxygen, and nitrogen.

Explanation:

Gerardus Johnannes Mulder conducted the experiments on proteins in 1938 and published them in paper "On the composition of some animal substances"  explaining about the chemical composition of several proteins in 1938.

He found that all proteins consists of carbon (C), hydrogen(H), nitrogen(N), and oxygen(O), in combination with sulfur and phosphorus. He also found that amino acids are the building blocks of proteins and contains carboxylic acid and amino groups in their structure.

Thus,all proteins contain carbon, hydrogen, oxygen, and nitrogen is the correct answer.
