Repair and Recombination of DNA Molecules

  • Edward A. Birge
Part of the Springer Series in Microbiology book series (SSMIC)

Abstract

Every organism has mechanisms for maintaining the integrity of its nucleic acid (i.e., for repairing any damage). Nevertheless, most organisms, including even bacteria and viruses, exhibit some sort of genetic exchange. The two processes may seem antithetical, as recombination, the movement of genetic information from one molecule of nucleic acid to another, implies that the nucleic acid undergoes some kind of structural alteration. However, as is discussed in this chapter, many of the steps involved in completion of the recombination process are the same as those involved in repair, and recombination can be looked on as a process in which tree potential for damage to the nucleic acid is outweighed by the potential benefit to be derived from the new genetic information.
