A judgment, based on infections that are totally preventable, somehow justifies "scientific" experiments on a bumbling, brainwashed public? Thaaankyou, very much mr scientist.
I'm so glad I don't understand you!

- Many transgenic plants are made using the bacterium Agrobacterium
- tumefaciens, which makes its living inserting its DNA into the genomes
- of various plants. Nonetheless, it is used to make transgenics that
- would not have existed without the intervention of the researcher. I
- understand that many people are concerned about introducing genes from
- one organism into another...personally, I am not. It is a judgenment
- call, and on that point, I am content to disagree.

- This is a misunderstanding of transgenics. The introduced genes are
- in fact integrated directly into a chromosome, usually in the nucleus,
- but sometimes in the chloroplast. They replicate and segregate right
- along with the rest of the DNA. This is the only way introduced
- genetic material can be maintained in the plant. Anything not
- integrated into a chromosome is lost. AFAIK, the introduced genes are
- no more likely to migrate into cells in the intestinal tract than any
- other gene we eat. If you can point me to evidence that indicates
- otherwise, I'd be very interested, especially in the mechanism.
- Documentation of horizontal gene transfer from ingested food would be
- a huge story in the field of genetics and evolution, but I've heard
- nothing of it.

- "Major disaster" is hyperbole IMHO...how many people have died from
- eating transgenic food compared to the number of deaths from
- contaminated spinach and peanuts and other instances of food
- poisoning? I agree that transgenic technology has its own set of
- problems, just like any other technology. Unfortunately, the loudest
- protests often do their own cause a disservice when they are based on
- misinformation.
