DNA four-way junctions (also known as Holliday junctions) are the primary structural intermediate during recombination, an important process responsible for biological evolution and maintenance of genomes. These junctions arise from the assembly of four nucleic acid strands to produce double-helical regions extending from a central point. Although much progress has...
Growth data compiled in this study were collected by using
pigs farrowed during the fall, 1963 and spring, 1964 farrowing seasons

Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo
boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...
