What exactly are computers used for in DNA sequencing?

Computers help scientists read the instructions inside our body’s DNA, like a very long book.

Imagine you have a super-long storybook, so long it would take forever to read. That's kind of what DNA is like for humans and animals. Scientists want to know what that story says, but it’s too long to read all at once. So they break the book into little pieces, like cutting up a big sandwich into small bites.

That’s where computers come in! They act like super-fast helpers who can read each bite quickly and put everything back together, just like you would if you had all the slices of your sandwich and wanted to know what it was before you ate it.

1. Scientists use special tools to copy parts of DNA, making many small copies.
2. These little bits are then read one by one, kind of like taking notes on each bite of your sandwich.
3. The computer takes all those notes and puts them in order, just like you would if you tried to put your sandwich back together.

This helps scientists find out what the DNA says, which can help us understand how our bodies work or even catch diseases early!
