Compare proteins to nucleic acids. Which of the following is TRUE?
A) Both have primary and secondary structure.
B) Both contain sulfur.
C) Both are used as templates to synthesize polymers
D) Both have monomers, which contain phosphorus.

Question

Quizplus · Accepted Answer

Both proteins and nucleic acids have primary structure (amino acid sequence in proteins and nucleotide sequence in nucleic acids) and secondary structure (alpha helices, beta sheets, etc. in proteins and base pairing in nucleic acids). Option B is incorrect since only proteins contain sulfur (due to presence of cysteine amino acid). Option C is partially correct as nucleic acids are used as templates for DNA replication and RNA transcription, while proteins serve as templates for protein synthesis. Option D is also incorrect as nucleic acid monomers (nucleotides) contain phosphorus, while protein monomers (amino acids) do not.
