One type of GM corn contains the amp gene that gives resistance to the antibiotic ampicillin.
There is concern that the digestion of this GM corn may result in the transfer of the amp gene to enterobacteria in the human intestine.
Which of the following explains why the transfer of genes from the plant to the bacteria is unlikely to happen?
1) An origin of replication and appropriate prokaryotic promoters are required for this amp gene to be expressed.
2) More than half of the enterobacteria isolated from human are amp resistant.
3) The bacteria are unable to take up any DNA released during the digestion of the plant without any vectors.
4) During digestion of the GM corn, all plant DNA is digested and destroyed by enzymes such as the human nuclease enzymes.
