National DNA database

Hi there!

So, you know how our body is made up of tiny cells? Well, each of these cells has a special code inside them called DNA. DNA is like a puzzle that tells our body how to work and what makes us unique.

Now, scientists can take a small amount of your DNA (like a cheek swab) and analyze it to see what makes you different from other people. This is called DNA testing.

A national DNA database is a big collection of these DNA tests from lots of different people. It helps the police and other investigators to solve crimes because they can compare the DNA found at a crime scene to the DNA in the database. If there's a match, it means they might have found the person who did the crime.

It's important to remember that only certain types of people can have their DNA in the database, like people who have been arrested or convicted of a crime. It's also important to make sure that our DNA information is kept private and protected.

So, that's a national DNA database in a nutshell. It's like a big library of our DNA information that helps keep us safe!
