Plot hole: How do they travel all over so quickly? Why does it take the same amount of time to travel from one continent as it does city to city? Someone in Paris talks to another in Zambia and bam, they're together all of a sudden.

Factual error: When they arrive at the hospital after Jackson is shot, they show alligators attacking people. Alligators are not native to Africa. Crocodiles would make much more sense, but I would assume either budget or behavioural differences prevented their use.
Other mistake: Whenever the sequence with the bear attack occurs, they're talking about brown bear information and show a video. The video they show depicts a black bear at one point.
Answer: In the episode "Blame It on Leo", Leo Butler, who use to work for Reiden, tells the group about the "mother cell." He explains it's Reiden's molecule vector. So it's something Reiden created. In real life science, vector cells are used to introduce DNA sequences from one organism to another. There are a variety of ways for this to occur, however, in the show not much explanation is given about how Reiden's mother cell works (and tends to bend how it works to the will of the plot).
