DNA fingerprinting

Okay, so you know how every person has a unique fingerprint on their fingers? Well, scientists have found out that our body has another type of unique fingerprint called DNA. DNA is like a long code inside our cells that tells our bodies what to do and how to look.

So, DNA fingerprinting is a way for scientists to identify someone based on their DNA code. To do this, they first need to get a sample of DNA from the person. This can be done by swabbing their cheek or taking a sample of their blood.

Once they have the DNA sample, scientists can start looking at the DNA code to see if it matches with other DNA samples. This is done by cutting the DNA into small pieces and then using a special machine to read the code of each piece.

If two people have the same DNA code, then they are most likely related in some way. But most of the time, each person's DNA code is unique to them, like their very own secret code.

DNA fingerprinting is used for a lot of important things, like solving crimes or figuring out who a biological parent is. It's kind of like being a detective and looking for clues in a person's DNA code to figure out who they are.
