The following steps are all involved in genetic recombination:

1. Screening for cells that contain the recombined gene.
2. Cutting the vector with restriction enzyme.
3. Mixing the gene of interest with the vector.
4. Isolating the gene of interest from its original source.
5. Ligating the gene of interest and the vector together.

The following sequence of these five steps would be typical:
O 1) 1, 2, 3, 4, 5
O2) 2, 3, 5, 1,4
O3) 5, 4, 3, 2, 1
4) 4, 2, 3, 5, 1
5) 2, 3, 5, 4, 1

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
