"Imagine your favorite toy has a secret message written on it, and we want to know if that same message is somewhere inside another toy’s special code."
DNA is like a long string of letters used by living things, such as Felis catus, which is the fancy name for a house cat. This string is made up of smaller parts called bases, and they come in four types: A, T, C, and G.
If we look at part of this string, like "... CATCAT...", it's like looking for a special pattern inside the code of a cat.
How We Check
We can compare the code from one cat to another. If the pattern "... CATCAT..." is found in that long string somewhere, then yes, it appears in the DNA of Felis catus.
It’s like searching through a big book, if you find your favorite sentence inside it, that means it's part of the story. In this case, we're looking for the word "CAT" repeated twice, like it's a fun little phrase in the middle of all that code."Imagine your favorite toy has a secret message written on it, and we want to know if that same message is somewhere inside another toy’s special code."

Examples
- A child sees the word 'cat' and wonders if it's in a cat's DNA.
- The word 'cat' is written in letters, but DNA uses nucleotides instead of letters.
- Sometimes parts of DNA repeat, like how 'CATCAT' might appear.
