Breaking Down DNA Mutations: Types and Their Impact Mutations are alterations in a DNA sequence that can have significant effects on protein synthesis and cellular function. Some mutations are harmless, while others can lead to severe biological consequences. In this blog, we’ll explore the four main types of mutations: silent, missense, nonsense, and frameshift , and examine their impact on proteins. 1. What Are DNA Mutations? A mutation is a change in the nucleotide sequence of DNA. These changes can occur naturally during DNA replication or be induced by external factors like radiation or chemicals. Mutations may: Have no effect on protein function. Alter the protein's structure or function. Completely disrupt protein synthesis. Mutations occur in codons, the three-nucleotide sequences in DNA or RNA that code for specific amino acids. 2. Types of DNA Mutations A. Silent Mutations A silent mutation involves a single nucleotide change, but it does not affect the amino acid produc...
