(1) Denaturation of Protein:
- Denaturation is the loss of a protein's native structure due to heat, pH change, or chemicals.
- Causes unfolding of protein chains, leading to loss of biological activity.
\[
\text{Protein (Native)} \xrightarrow{\text{Heat}} \text{Protein (Denatured)}
\]
(2) Nucleic Acid:
- Nucleic acids (DNA, RNA) store genetic information.
- Composed of nucleotides: sugar, phosphate, and nitrogen base.
