Updated: Share Article AAA DNA tests help a great deal in diagnosing genetic disorders and diseases transmitted genetically, former Vice-Chancellor of Karnatak University Pramod Gai has said. He was inaugurating ‘DNA testing’ organised as part of National Science Day at Dharwad Regional Science Centre in Dharwad on Tuesday. Prof. Gai said as it had already been established, the human body had thousands of cells and some people inherited genetic disorders from parents. DNA tests could identify such diseases or disorders, he said. He said it had now been established after diagnosing human body cells through DNA tests that diseases inherited through blood relationships were more. And identifying diseases was comparatively easier now with advent of technology, he said.
