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.

A vision-driven change agent with a career-long record of community outreach, leadership development, marketing, and communications success for leading organizations.

This talk was given at a local TEDx event, produced independently of the TED Conferences. Что, если все книги по тайм-менеджменту были написаны лишь для рациональной половины человечества? Что делать, если вы принадлежите ко второй половине? Если все ваши усилия по планированию приводят к нулевым результатам? Как избавится от чувства вины при виде бесконечного списка отложенных дел? И можно ли выжить во всем этом хаосе?

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Что общего у законов христианской морали и правил поведения при пожаре? Почему за то, за что сейчас мы уважаем человека, пятьдесят лет назад его могли убить.

Мы живем в мире правил и игнорировать их нельзя. Вы можете быть конформистом или нонконформистом, но плывёте вы по течению или против течения, вы всё равно внутри потока.
