Despite their heft, many dinosaurs had surprisingly tiny genomes
...opods yet." Organ and Edwards say the clear-cut dichotomy
in dinosaur genomes is likely due to different amounts of repetitive and non-coding DNA in the two groups' genetic material, a factor largely responsible for variation in genome size across animal species. They estimate that active repetitive DNA mig...
A dichotomy in migration patterns found for sea turtles in east Atlantic
... West Africa, researchers have found an unexpected dichotomy
in turtle behavior: While some turtles leave the nesting grounds to feed on bottom-dwelling sea life in shallow coastal waters, others leave Cape Verde to roam the much deeper open ocean along the African coast and exhibit a distinct feeding strategy...
Random gene expression may drive HIV into hiding
...expression on high and others turned it off. This dichotomy
in cell fate from genetically identical cells is consistent with the idea that random fluctuations in gene expression control what happens to the cells, the researchers said. To see if this really was the best explanation, they conducted a large arra...
