Mutation types | Silent mutation | missense mutation | nonsense mutation | frameshift mutation

Types of Mutations:

Mutations are changes in the DNA sequence that can affect how proteins are made. Here’s a simplified overview:

1. Silent Mutation: A change in the DNA sequence that doesn’t alter the resulting protein. It’s like fixing a typo that doesn’t change the meaning of a sentence.


2. Missense Mutation: A single DNA change leads to a different amino acid in the protein, potentially altering its function. Think of it as swapping a word in a sentence, which might or might not change its meaning.


3. Nonsense Mutation: This creates a premature stop signal in the DNA, cutting the protein short. It’s like ending a sentence abruptly.


4. Frameshift Mutation: Adding or removing DNA bases shifts the reading frame, scrambling the protein instructions. Imagine deleting a word in a sentence, making the rest of it unreadable.
