Microbial populations achieve genetic diversity through horizontal gene transfer. Bacteria may transfer genes from one to another by conjugation, transformation, or transduction. Scientists often exploit these processes through recombinant DNA.
Peer into the microbial world with this comprehensive microbiology series. This series helps students understand microbial functions and how microorganisms affect everything from medicine to environmental issues to global politics. Dynamic visuals — such as animations and scanning electron micrographs — and case studies including DNA testing and dramatic battles against dangerous viruses illustrate the work and effects of microorganisms. Students gain an enhanced appreciation of the field of microbiology as they meet scientists carrying on their investigations in the lab and in the field. Unseen Life on Earth is designed for general microbiology courses for majors and allied health students. It is also useful as a resource for life science courses in college and high school.
