What are endonucleases?

Endonucleases are like tiny scissors that cut DNA apart.

Imagine you have a long string of beads, and each bead represents a piece of information in your body. Now imagine someone comes along with special scissors that can cut the string in the middle, not just at the ends. That’s what endonucleases do to DNA, which is like a super-long string of beads inside our cells.

Think of DNA as a ladder made of rungs. Endonucleases find specific places on this ladder and snip it right there, just like a pair of scissors cutting through the middle of a ribbon.

These tiny scissors are used by cells to do all sorts of things, like fixing mistakes in our DNA or making new combinations when we have babies. It's like having a special tool that helps your body change and grow, not magic, but very smart work!
