61.   Therefore, the Department concluded, the new genes would not be enough to turn wild relatives into superweeds.

62.   They also want to see the population of corrected cells increase over time as the cells carrying the new genes divide and multiply.

63.   They inserted a new gene into the mousepox virus, a weak cousin of the human disease smallpox.

64.   To control the experiment, neither Herndon nor the other researchers know which joints got the cells with the new genes.

65.   Traditional plant breeding tries to introduce new genes through pollen transfer, or sexual reproduction, from one plant to another.

66.   What if a new gene moves from a modified plant to an unmodified bystander?

67.   What if the new genes worked too well, and could not be turned off?

68.   When fly people find a new gene, they give it a colorful name, like Tudor or rutabaga.

69.   When the mosquito eats, the new gene manufactures a protein that covers the wall, effectively covering the locks that the plasmodium needs to turn to escape.

70.   Wilson is now working with a new gene delivery system, one based on a small virus called adeno-associated virus.
