The highly variable range of human genetic mutations induced by bacteria have been identified with some success by researchers with the Human Genome Project. Rather than serving as markers of particular diseases, such mutations generally mark the presence of those pathogens capable of affecting DNA transcription and translation in the nucleus. | The highly variable range of human genetic mutations induced by bacteria have been identified with some success by researchers with the Human Genome Project.
