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. Nitrogen bases form the backbone of a nucleic acid.
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: -The main difference between nucleotide and nucleic acid is that nucleotide is the monomer of nucleic acid whereas nucleic acid is a chain of nucleotides, which is capable of storing genetic information in the cell.
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: -Nucleotides are linked to each other repeatedly in long strands by the formation of phosphate ester bonds. These long strands of bonded nucleotides make up a nucleic acid. Nucleic acids are polymers. They are composed of a chain of nucleotides, which are linked by phosphodiester bonds.
