DNA Polymerase Choices Shape the Noise in Short Repeat DNA Tests
The way scientists amplify DNA for tests depends heavily on the enzyme they pick. Thermostable DNA polymerases are used in PCR to copy DNA accurately, but mistakes can sneak in. These errors matter when scientists look for tiny changes, like a single mutation in a patient’s sample or the DNA of a mi
