Functional cloning is when scientists make a copy of a gene from an organism (like a plant or animal) and put it into another organism to see what it does.
Think of it like taking a piece from one puzzle and putting it in a different puzzle to see if it fits and changes the picture.
Scientists use different methods to make the gene copies and to put them into the new organism. Once the gene is in the new organism, they can watch what happens and see if it is doing the same thing as it did in the original organism.
This helps scientists learn more about how genes work and what they do. It can also help them create new organisms with desired traits, like making a plant that grows faster or an animal that is resistant to disease. However, it is important for scientists to carefully consider the ethics and consequences of creating new organisms through functional cloning.
