The Primary Structure of a Protein is Determined by ________

Question

The primary structure of a protein is determined by ________.
A) the sequence of amino acids
B) hydrogen bonds formed between the components of the peptide linkage
C) a series of helical domains
D) pleated sheets
E) covalent bonds formed between fibroin residues

Accepted Answer

The primary structure of a protein is determined by the sequential arrangement of its amino acid residues. This sequence of amino acids is encoded by the genetic code and ultimately determines the protein's unique shape and function. Hydrogen bonds, helical domains, pleated sheets, and covalent bonds between fibroin residues are all secondary or tertiary structural features that arise from the primary structure.
