Who is DNA Cleavage?

DNA cleavage is when special tools cut up the long string of letters that makes up DNA.

Imagine your favorite toy, like a building block set, each block has a letter on it, and all the blocks together make a message. That’s kind of what DNA is: a long chain of letters that tells our bodies how to grow and work. Now, DNA cleavage is like having a pair of scissors that can cut this string at specific spots.

Think of your toy blocks again, if you have a special pair of scissors that only cuts between certain blocks, say the red ones, then every time you use them, they’ll only break apart where those red blocks are. That’s what DNA cleavage does in real life: it finds specific places on DNA and cuts them, helping scientists study or change genetic messages.

Sometimes, we want to fix a message, like changing one letter in your toy chain so the whole message reads differently. Scientists use these special scissors (called enzymes) to do that, just like you might use real scissors to cut out a letter from a word in a book.
