CNN —A piece of woolly mammoth skin excavated from the Siberian permafrost has been found to contain fossil chromosomes in a first-of-its-kind discovery, according to a new study. The new study revealed that fossils of ancient chromosomes survive in this skin sample. But the DNA from elephants was also needed to assemble the mammoth genome. The researchers hope to use the findings to assemble the woolly mammoth genome completely. “This structural information provides insights into functions of the woolly mammoth genome that were invisible using previous genomic methods,” Heintzman said in an email.
