The secondary structure of a protein refers to

  • Correct answer
    A
    $\alpha$-helical backbone
  • B
    hydrophobic interactions
  • C
    sequence of $\alpha$-amino acids
  • D
    fixed configuration of the polypeptide backbone

Solution

Secondary structure involves $\alpha$-helical and $\beta$-pleated sheet like structure. Where as Primary strucure involves sequence of $\alpha$-amino acids polypeptide chain.

Hence, the correct answer is option: 'A'.
