Question

When a protein such DNA ase enzyme gets denatures with heat, it means that which option is correct?

1. the primary structure is destroyed

2. peptide bonds between amino acids are destroyed

3. secondary and tertiary structures are destroyed

Answer 1

Option 3 is correct.

Explanation:

The IUPAC definition of denaturation is the process of partial or total alteration of the native secondary, tertiary, or quaternary structures of proteins or nucleic acids resulting in a loss of bioactivity.

So when a protein is denatured, it loses its secondary and tertiary structure.
