In search of a low-allergy peanut, many people are allergic to substances in the environment. of the many foods that contain allergens (allergy-inducing substances), peanuts cause some of the most severe reactions. mildly allergic people may only get hives. highly allergic people can go into a form of shock. some people die each year from reactions to peanuts. a group of scientists is attempting to produce peanuts that lack the allergy-inducing proteins by using traditional selective breeding methods. they are searching for varieties of peanuts that are free of the allergens. by crossing those varieties with popular commercial types, they hope to produce peanuts that will be less likely to cause allergic reactions and still taste good. so far, they have found one variety that has 80 percent less of one of three complex proteins linked to allergic reactions. removing all three of these allergens may be impossible, but even removing one could . other researchers are attempting to alter the genes that code for the three major allergens in peanuts. all of this research is seen as a possible long-term solution to peanut allergies. how does altering the dna of a peanut affect the proteins in peanuts that cause allergicreaction?
1) the altered dna is used to synthesize changed forms of these proteins.2) the altered dna leaves the nucleus and becomes part of the allergy-producing protein.3) the altered dna is the code for the antibodies against the allergens.4) the altered dna is used as an enzyme to break down the allergens in peanuts.
allergic reactions usually occur when the immune system produces: ) antibiotics against usually harmless antigens.2) antigens against usually harmless antibodies.3) antibodies against usually harmless antigens.4) enzymes against usually harmless antibodies.
