DNA is inside your blood which is inside your body. Blood takes up 7 to 8 pounds of a person's body weight and one quarter of that is DNA! Did you know one drop of blood contains one billion strains of DNA!
Mosquitos show a example of extracting DNA. How?
When a mosquitos digs into your body it sucks out blood. In the Intro it says blood contains DNA. So that means mosquitos can carry blood from other animals such as a dinosaur.
Sometimes the bug will land on a branch and get stuck in sap. Over thousands of years the sap will turn hard like a rock. This fossilized sap is called amber.
When a scientist finds the bug trapped in amber they will try to pull the amber off and extract the blood that contains the dinosaur DNA.
Why is DNA important? DNA is important because DNA is what builds us humans, animals, and insects up to live on earth.
DNA only lasts about 1 to 2 million years!
One drop of blood contains 1 billion strains of DNA
If you pulled DNA out of a cell it would be as long as 2m
Humans have approximately 10 trillion cells so if you were to line all the DNA found in a human body it would stretch from Earth to the Sun 100 times
