Mutations in DNA can change how living things look and act. Sometimes, these changes can be pretty bad for them.

Types of Mutations:

1. Point mutations: This is when just one tiny part of the DNA changes.
2. Insertions: Here, an extra piece of DNA gets added in.
3. Deletions: This is when a piece of DNA gets removed.

All of these can mess up the way proteins are made, which are super important for how our bodies work.

Consequences:

When proteins change, they might not work right anymore. This can lead to traits or features that can be harmful.

For example, if just one small part of the DNA changes, it can cause a genetic disorder. This might affect things like how a person grows, how they break down food, or how their immune system fights off sickness.

But there is hope! Scientists are looking at ways to fix these problems.

Two promising solutions are:

1. Gene therapy: This aims to fix or replace the faulty parts of DNA.
2. CRISPR technology: This allows scientists to target specific mutations and correct them.

Still, there are some challenges. People worry about the ethics of these technologies. Plus, there are technical hurdles to overcome. So, finding solutions to these problems is not easy.
