New genes created by genetic engineering produce brand new proteins called "novel" proteins. All proteins have the potential to trigger allergic reactions under certain conditions. Novel proteins are not recognized by the human immune system. In most cases, these proteins are tested in petri dishes rather than the plant itself.

What information did you include in your answer?

Novel proteins may be beneficial to human health.

Novel proteins may cause allergic reactions.

Additional reactions may occur once the protein is introduced to the plant, which could have negative effects on human health.
