Using the DCodeTM System to Identify DNA Sequence Variation for Studies of Population Structure in Marine Organisms

Introduction DNA polymorphisms are useful tools for ecological and evolutionary studies of both terrestrial and marine organisms, with applications ranging from species identification to delineation of population structure to monitoring genetic change in wild or domesticated populations. Denaturing gradient gel electrophoresis (DGGE) using the DCode universal mutation detection system provides a convenient means of identifying genes with useful levels of polymorphism, and subsequently screening populations for variation at selected loci.
