Question

Protein molecules are composed of long chains of _______. A. DNA B. ribosomes C. amino acids D. RNA

Answer 1

The correct answer would be C. amino acid.

The protein or polypeptide chain is a polymer of amino acids.

The amino acids are attached to each other through a peptide bond.

The amino acid sequence of the protein is determined by the nucleotide sequence of the DNA.

The amino acid sequence determines the folding of the proteins into the three-dimensional structure.

This three-dimensional structure specifies the function of the proteins.

Answer 2

The correct answer that would complete the given statement above would be option C. Protein molecules are composed of long chains of amino acids, which are linked to its neighbor through a covalent peptide bond. Each type of protein has its own unique sequence of amino acids.
