Chapter 14: At a Glance DNA Recombination in Nature DNA recombination occurs naturally through processes such as sexual reproduction, bacterial transformation, and viral infection. Recombination provides raw material for evolution. There are both similarities and differences between recombination in nature and in the laboratory. Recombinant DNA Technology A DNA library consists of DNA from a particular organism inserted into bacterial plasmids. The genes of interest must be identified in the DNA library. Selected DNA sequences in the library can be amplified. Amplified genes can be used for research, industrial, medical, or agricultural purposes. Locating Genes Restriction enzymes can be used to provide markers on a chromosome. Restriction fragment length polymorphisms can be used to locate a gene. Sequencing Genes Reflections on the Ethics of Biotechnology Some uses of biotechnology have social impacts. Bioengineered organisms may be released into the environment. Biotechnology may eventually allow alterations in human genomes. Designed in cooperation with Andrew Stull and Steven Brunasso. Last Update - July 25, 1997
