The Departed (2006)

Correction: It's on his temple, not his forehead. This is visible later.

Jurassic Park (1993)

Corrected entry: When the doctor is showing off the piece of amber that they have gotten the DNA from, there is a problem. The mosquito in the amber is a male, as one can tell by the antennae. Because it is only the female mosquito that feeds on blood, the male should only have nectar in its stomach. To make it worse, in that species of mosquito, Toxirhynchites, both the males AND females are flower feeders, and would therefore have no blood, or dinosaur DNA in their stomachs. (00:25:00)

Correction: Can we not just assume that the mosquito in Amber in the cane is just symbolic and doesn't necessarily have to be the exact species and gender of the mosquitoes that yielded the dino blood and DNA?

Using the actual mosquito will have more meaning to Hammond than a random one. John is also shown to want only the best.

I don't know. I would think that a mosquito preserved in Amber containing dinosaur blood would be exceptionally rare and probably not the kind of thing you'd waste on a cane.

Correction: Hammond's company, InGen, did not deal exclusively with dinosaurs. Dr. Ellie Sattler, the paleo-botanist, observed and mentioned that Jurassic Park was also full of ancient and extinct plant life. InGen used the same process to procure vegetable DNA from ancient insects (such as the Toxirhynchites mosquitoes) that fed on vegetable matter. It's the same process.

Plant sap is composed mostly of water and dissolved sugars, hormones and carbohydrates. It does not contain any DNA.

Incorrect. Plant genomics research shows that plant fluids do, indeed, contain plant DNA. Moreover, a single mosquito could yield the DNA of several different plants, as well as the mosquito's own DNA and the DNA of microbes consumed along with the plant fluids.

Correction: The mosquito in the amber is not one that supplied the DNA for the dinosaurs. We know this because there is no drill hole for the extraction. When the extraction process is shown, a hole several millimetres across is drilled into the amber.

Correction: Plant sap consists of water, some simple sugars, more complex carbohydrates and plant hormones. It does not contain any DNA at all.

It's about the mosquito inside the amber, not the amber itself. Anyway, plant sap most definitely contains DNA, just plant DNA. All living organisms have DNA.

Plant sap does not contain DNA. Phloem sap consists primarily of sugars, hormones, and mineral elements dissolved in water. DNA is polar due to its highly charged phosphate groups and dissolves easily in water. Transporting dissolved DNA would be utterly pointless.

Fine, the amber doesn't contain DNA (it's fossilized anyway). It's still a bad correction.
