Where did you come from Mr. DNA?
From one drop of your blood, we can find billions of strands of DNA. These are the building blocks of life. It is the blueprint for all living things and even extinct animals like dinosaurs. A hundred million years ago, mosquitoes fed on the blood of animals, even dinosaurs. After biting a dinosaur, the mosquito would land on the branch of a tree and get stuck in the sap. The tree sap becomes fossilized, preserving the mosquito inside. This amber sits for millions of years with the mosquito inside, until scientists from Jurassic Park came along. They extract the preserved blood from the mosquito using sophisticated techniques and bingo, dino DNA!
