2025
Genetically Modified Organism - answer A popular term for a transgenic
organism, usually referring to an agricultural plant or animal.
Summarize the Aqua Advantage Genetically Engineered Salmon or
"Frankenfish". - answer Scientists took a normal wild-type salmon and
used its segments of DNA/ a growth hormone from fish, then engineered it
into a modified fish. It is designed to grow twice as fast.
Recombinant DNA - answer An artificially constructed DNA molecule
formed by joining segments of DNA from different sources. (i.e. injected
into Atlantic Salmon)
What two fish contribute to make the Frankenfish? - answer The
AquaBounty fish is an Atlantic Salmon with genes from other fish. It
contains a growth hormone gene from a Chinook Salmon and a genetic "on
switch" from the Ocean Pout.
How does the genetically-engineered fish work? - answer It is a
combination of a growth gene from a chinook salmon (to accelerate
growth) and genetic material from an ocean-pout (allows fish to grow
year-round).
What does the induciton of triploidy result in? - answer A triploid fish is
merely a fish that is sterile. The genes of the fish have not been
manipulated or changed in any way, but the fish cannot reproduce.
Why is triploidy important for the engineered salmon? - answer It
renders most of the fish as sterile and reduces the risk of interbreeding
with wild-type fish and further increasing growth by removing stress of
reproduction.
, What was the purpose of the Frankenfish? - answer Its purpose was to be
modified to grow faster and get to consumers faster with the intention of
being consumed.
How did the FDA respond? - answer The FDA analyzed data and
information and concluded that AquaAdvantage met the requirements for
approval, including that the fish is safe to eat.
Why was the FDA's decision important for consumers? - answer The FDA
determined there was no biological difference between salmon and the
company does not have to use a label to identify its food.
How did the public respond to the GMO fish? - answer The public were
concerned there were health and environmental risks associated with the
salmon. A fishing organization stressed this would hurt fishers financially,
so the GMO fish cannot be sold in the United States, but is distributed
around the world.
What are Roundup Ready Soybeans? - answer These are a type of GMO
crops that make up more than 90 percent of U.S. harvest.
What is Roundup Ready soybeans resistant to? - answer They are
resistant to glyphosate.
What is glyphosate? - answer It is a herbicide used to kill weeds on crops
and is an active ingredient in Roundup. It is the most-used chemical
product ever.
Herbicide - answer A substance used to destroy plants, especially weeds.
What essential amino acids in plants are interfered with the herbicide? -
answer Phenylalanine, Tyrosine and Tryptophan
