Humans Share 99% Of The Same DNA4-人类共享着99%相似的基因

 

Did you know that all humans have almost exactly the same DNA? DNA is the genetic5 information that gets passed on when cells reproduce. It is found in every living organism. More than 99% of your DNA is the same as every other human’s in the world. In recent years, scientists concluded that even humans living on opposite corners of the earth share almost the same DNA. DNA samples are used for paternity tests, health screening tests, and forensic tests. The tiny differences in our DNA make a big difference in the courtroom.
