Question

Which of the statements about “Denaturation” given below are correct?
(1) Denaturation of proteins causes loss of secondary and tertiary structures of the protein
(2) The coagulation of egg white on boiling is a common example of denaturation.
(3) Denaturation affects primary structure which gets distorted

• A. (2) and (3)
• B. (1) and (3)
• C. (1) and (2)
• D. (1), (2) and (3)

Answer 1

The correct option is C (1) and (2)

Denaturation does not change the primary structure of protein. The coagulation of egg white on boiling is a common example of denaturation.During denaturation secondary and tertiary structures are destroyed but primary structure remains intact.
