To measure genetic diversity, Nowak's team sequenced genes in the animals» mitochondria — energy - generating cellular organelles that have their own small genome. (scientificamerican.com)
By sequencing the genes of a population of cells that all contain the program, researchers can determine the magnitude and duration of the signal: The more cells have the genetic mutation, the stronger or longer the signal was. (sciencemag.org)
Within decades, advances in sequencing genes from ancient tissue could allow scientists to clone extinct dodo birds, saber - toothed cats, and woolly mammoths, says Jeffrey Yule, an evolutionary ecologist at Louisiana Tech University. (discovermagazine.com)
