According to the CBC [Canadian Broadcasting Corporation], researchers at Trent University sampled both the oven roasted chicken filets and the chicken strips that Subway uses on its sandwiches in Canada. After testing six small samples of the filets and three small samples of the strips, the researchers ran a DNA test.

The results showed that the filets contained just 53.6 percent chicken DNA. The strips were found to contain just 42.8 percent chicken DNA.

CBC reports that the rest of the DNA found in the chicken was soy — used either for either seasoning or filler.

    Why is the above even modded informative? That's for testing for the existence of stuff, not the _proportion_ which is what this story is about.

    https://en.wikipedia.org/wiki/Polymerase_chain_reaction [wikipedia.org]

    Polymerase chain reaction (PCR) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.

    e.g. it amplifies the tiny bit of DNA you have.

    So that's useful for knowing if you have soybean or rat in something when you shouldn't. But how is that going to help with _accurately_ figuring out the proportion of soybean vs chicken by mass?
