Все, что нужно знать об открытии, редактировании и функциях ДНК.
#биология #ДНК
В курсе рассказано о самых фундаментальных аспектах ДНК, особенно о тех, при изучении которых особую роль играют не только биология и генетика, но и химия, физика и математика: как была открыта структура ДНК и почему это открытие считается одним из крупнейших в истории науки; об асимметрии всего живого в отношении правого и левого; о центральной догме молекулярной биологии — универсальном законе живой материи; о том, почему ДНК бывают линейными у одних организмов и замкнутыми в кольцо у других; о мутациях, повреждениях текста ДНК, ведущих к многочисленным наследственным болезням; о возникающей на наших глазах революционной технологии редактирования ДНК, которая позволит в недалеком будущем исправлять ошибки в тексте ДНК больного.

Emma Slade, author or Set Free and founder of the charity Opening Your Heart to Bhutan, talks about her path to buddhist, and the situation in which she found herself which caused this change. Emma was previously a successful investment banker and talks about the dichotomy between her current life and her previous occupation, and how this has allowed her to view the world in a fresh light.
Emma was born in Kent and was educated at universities in Cambridge and London. She had an exciting international career in finance which she committed to with mental drive and a tasteful selection of suits. But a deep seated desire to enquire into the deeper aspects of what it is to be a human being was brought to the surface following a life-changing visit to Jakarta, Indonesia. She resigned from her financial career and began travelling and exploring yoga and meditation. Since then she has taught yoga and meditation for over 15 years and continued to deepen a life — long interest in Buddhism.
