Mutations are really fascinating because they can change how proteins work in different ways. Let’s break down the types of mutations and what they do:
Point Mutations: These are tiny changes, like switching out just one letter in the DNA code. Sometimes, this change doesn't affect anything at all, and we call that a silent mutation. Other times, it can change an amino acid, leading to something called a missense mutation. This might change how the protein works. In some cases, it can even create a stop signal where one shouldn’t be, resulting in a nonsense mutation. This can make the protein shorter and often not useful.
Insertions and Deletions: These mutations add extra letters to the DNA or take some away. They can change how we read the genetic code (this is known as frameshift mutations), which means all the following amino acids might change too. This can really mess up how a protein functions.
Large-scale Mutations: These are bigger changes that might involve copying parts of DNA or rearranging big chunks of it. They can create new proteins or change how genes are turned on and off.
In short, mutations can either make small changes to proteins, changing how they work, or they can completely break them. Sometimes a mutation can be helpful, but often it can stop the protein from working properly.
