Point mutations can change how proteins work and affect our health. Let’s break it down:

• Types of Mutations: There are three main kinds of mutations:

  • Missense Mutation: This changes one amino acid in a protein.
  • Nonsense Mutation: This leads to a premature stop in making the protein.
  • Silent Mutation: This does not change the protein at all.

• Protein Function: Just one small change in an amino acid can change the whole shape of a protein. This can affect how well the protein works.

• Health Impacts: Some of these mutations can cause serious diseases. For example:

  • Sickle cell anemia affects red blood cells.
  • Cystic fibrosis affects the lungs.

This shows why studying genetics is so important! It helps us understand our bodies better and how they stay healthy.
