Genetic Engineering

What is a GMO?

• An organism that has its DNA modified by humans

• An organism missing a chromosome

• another name for selective breeding

• A genetically identical organism

Putting the gene for bioluminescence into a fish (so that it will glow or be fluorescent) is an example of...

• Genetic Engineering
• Selective Breeding
• Artificial Selection
• Gene Mutation

DNA can be spliced (or cut) out of the genome of one organism in order to insert it into a different organism using

• prescription enzymes
• digestive enzymes
• restriction enzymes
• transcription enzymes

Human DNA is inserted in bacterial DNA in order to create the human insulin protein. Such DNA is called

• viral DNA
• bacterial DNA
• recombinant DNA
• transcribed DNA

Possible advantages of genetically modified crops include(s)

• insect resistance
• drought/freeze resistance
• make them more nutritious

• all of these are possible advantages of creating GMOs

Concerns about genetically modified organisms include(s)

• risk to human health
• may be harmful to ecosystems
• seed/pollen drift to organic farms
• all of these are valid concerns

What is recombinant DNA

• DNA from 2 different species combined

• DNA from 2 different ribosomes

• DNA that is separated out from a vector

Which of the following could be used as a vector for a human gene?

• bacterial plasmid

• ribosomes

• A mitochondria

• mRNA

"Transgenic" refers to an animal that:

• Has DNA from another organism spliced into its genome

• Has both plant and animal DNA

• Has unique genes for its species

In which ways can genetic engineering can improve crops

• Make them pest or drought resistant

• Make them more nutritious

• Larger yield (greater amount of food produced)

• All answers are correct
