Copy machines are handy in schools and offices because they can quickly duplicate pages from all types of sources. Similarly, biologists often need to make many, many copies of genetic material. They use a technology called PCR. It’s short for polymerase (Puh-LIM-er-ase) chain reaction. Within just a few hours, this process can make a billion or more copies. ...
