Sure! So, let's start with what DNA is. Imagine a long string of beads, each bead being a different color. This string is called DNA and it contains instructions for making all the different parts of your body.
Now, imagine that each group of three beads in the string is like a special code. This code is called a codon. Each codon tells your cells what specific building block to make for your body.
For example, let's say there's a codon that has the beads "A-U-G." This codon tells your body to make the building block called Methionine. And there's another codon that has the beads "C-U-C." This codon tells your body to make the building block called Leucine.
So, codons are like special codes that help your cells know exactly what to make so that you can grow and function properly. It's like a secret language that only your cells know how to read.
