Question

complete the table to compare the structures of a protein and dna.
has hydrogen bonds between nitrogenous bases
has two strands of nucleotides joined together
forms a double helix

Explanation:

• Has hydrogen bonds between nitrogenous bases: DNA has hydrogen bonds between its nitrogenous bases (A - T, C - G). Proteins do not have nitrogenous bases with hydrogen bonds in this context.
• Has two strands of nucleotides joined together: DNA is made of two strands of nucleotides. Proteins are made of amino acids, not nucleotides in two - strand form.
• Forms a double helix: DNA has a double - helix structure. Proteins have various structures (primary, secondary, tertiary, quaternary) but not a double - helix like DNA.
