A gene that comes from the same organism to make a GMO can best be described as... 
(ex: gene from corn placed into corn plant) 

• cisgenic 
• transgenic 

A gene that comes from the different organism to make a GMO can best be described as... 
(ex: gene from corn placed into a tomato plant) 

• cisgenic

The toxin Bt (bacillus thuringiensis) comes from a ______ cell. 

• bacteria
• protist
• corn plant 
• fungus 

Why do scientists use bacteria to genetically modify a crop?

• Bacteria can cause disease (i.e. can attack!) in plants & easily enter the plant's cells.

• Bacteria has the ability to transfer a portion of its DNA into plant cells.

• The bacteria plasmid is a vector with the gene of interest & helps to incorporate its DNA with the crop's DNA.

• All of the above!

A circular, round, carrier molecule of DNA that allows the gene of interest to be copied is best known as a....

• transformation 
• restriction enzyme 
• vector or plasmid
• recombinant DNA
