Question

complete the table to compare the structures of a protein and dna.

	protein	dna
has two strands of nucleotides joined together
forms a double helix

submit

Explanation:

• Has hydrogen bonds between nitrogenous bases: DNA has nitrogenous bases (A-T, G-C) with H - bonds. Proteins don't have nitrogenous bases with such bonds. So Protein: No, DNA: Yes.
• Has two strands of nucleotides joined together: DNA is double - stranded (nucleotides). Proteins are made of amino acids, not nucleotide strands. So Protein: No, DNA: Yes.
• Forms a double helix: DNA's structure is a double helix. Proteins have different structures (e.g., primary, secondary, etc.). So Protein: No, DNA: Yes.

Answer:

	Protein	DNA
Has two strands of nucleotides joined together	No	Yes
Forms a double helix	No	Yes
