|
|
Nucleotides link together to form a nucleic acid. Amino acids link together to form a protein.

|
|
A nucleic acid is held together by the sugar-phosphate complex. A protein is held together by the carbon-carbon bonds.
|
Detailed explanation-1: -Which statements explain the primary difference between the structure of a nucleic acid and the structure of a protein? A nucleic acid has alternating base pairs. A protein has alternating peptides.
Detailed explanation-2: -Protein is a molecule made up of polypeptides. It is a class of biological molecule consisting of chains of amino acids called polypeptides. Nucleic acid is a class of macromolecules made up of long chain of polynucleotide that includes deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Detailed explanation-3: -Nucleotide: Nucleotide is composed of a phosphate group and a nitrogenous base, which are attached to a pentose sugar. Nucleic Acid: Nucleic acid is composed of a chain of nucleotides, which are linked by phosphodiester bonds.
Detailed explanation-4: -An amino acid is a monomer of a protein molecule while a nucleotide is a monomer of a nucleic acid. Therefore, this is the key difference between amino acid and nucleotide. Moreover, the amino acid has C, H, N, O and S atoms while nucleotide has C, H, N, O and P atoms.
Detailed explanation-5: -Which of the following best describes the difference between the functions of nucleic acids and enzymes? Nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions. Some proteins catalyze biochemical reactions.
