mRNA display is like a cooking show where a chef shows you all the ingredients they are using to make a dish. But instead of cooking, scientists use mRNA (a special kind of genetic code) to show all the possible proteins that can be made.
Think of it like a recipe book. The mRNA shows all the different recipes for proteins, and the scientists can use it to see what kinds of proteins are possible. They can then look at the recipe (mRNA) and figure out how to make and study the protein (the dish).
This can help scientists understand how proteins work and how they interact with other things in the body. It's like making a list of all the possible things you could make for dinner and figuring out which ones are the best by looking at the ingredients and how they work together.
Overall, mRNA display helps scientists understand the different proteins that can be made in our bodies and how they work.
