biophysicist and embryologist, born in Yerevan. Led the Soviet team that cloned a mouse ("Masha") from an embryonic cell in 1987, years before Dolly the sheep (1996) made cloning world-famous — Dolly's specific breakthrough was cloning from an *adult* cell, a harder problem Chailakhyan's team did not attempt, so the two results are related but not identical.
