A Novel Role of Ring Chromosomes as Evolutionary Drivers of Herbicide Resistance
In eukaryotes, chromosomes are linear structures; in contrast, a ring-shaped chromosome is a rare structure that results from the fusion of broken ends of linear chromosomes. Ring chromosomes may be induced by radiation or may occur spontaneously. In humans, ring chromosomes occur in approximately 1:50,000 embryos, and often are associated with growth deficiency and disease. […]
