WEBVTT 00:00:00.000 --> 00:00:02.871 By ARTE France Scientifilms 00:00:05.112 --> 00:00:08.014 Our hands, our eyes , our face 00:00:08.104 --> 00:00:10.922 our all body is an aggregate of billions of cells. 00:00:11.362 --> 00:00:14.252 At the heart of each of them is nestled the DNA, 00:00:14.252 --> 00:00:15.652 the one that we received from our parents 00:00:15.652 --> 00:00:18.032 and that we'll transfer to our children. 00:00:19.018 --> 00:00:21.138 What is exactly passed 00:00:21.138 --> 00:00:22.558 from one generation to the other, 00:00:22.558 --> 00:00:24.138 from one cell to the other? 00:00:24.138 --> 00:00:26.138 We know that DNA is transmitted 00:00:26.138 --> 00:00:28.588 but not only DNA. 00:00:30.376 --> 00:00:31.156 Identical twins 00:00:31.156 --> 00:00:32.226 have the same DNA, 00:00:32.226 --> 00:00:33.186 the same genome, 00:00:33.956 --> 00:00:36.666 and nonetheless have physical differences. 00:00:36.666 --> 00:00:39.776 How is that possible? 00:00:39.776 --> 00:00:42.256 The genome has been considered like a book 00:00:42.256 --> 00:00:44.006 and indeed book's editions can be 00:00:44.006 --> 00:00:45.976 very different from each other. 00:00:47.000 --> 00:00:48.850 Scientist have assumed for a long time 00:00:48.850 --> 00:00:51.490 that DNA ruled our biologic destiny. 00:00:53.730 --> 00:00:57.120 Nowadays they're discovering a new world: 00:00:57.319 --> 00:01:00.609 we're becoming more and more aware that 00:01:00.609 --> 00:01:03.119 DNA doesn't explain everything. 00:01:03.119 --> 00:01:05.219 And more and more capable of cultivating 00:01:05.219 --> 00:01:08.679 the ideas about the impact of the environment. 00:01:09.018 --> 00:01:10.488 All around the world, 00:01:10.488 --> 00:01:13.018 biologists are investigating this new mystery. 00:01:13.849 --> 00:01:15.139 My job is to look into 00:01:15.139 --> 00:01:15.949 the cellular nucleus 00:01:15.949 --> 00:01:16.949 for new knowledge 00:01:16.949 --> 00:01:20.319 and to reach places that people have never reached before. 00:01:20.574 --> 00:01:21.904 A scientific adventure 00:01:21.904 --> 00:01:24.644 in which we seek to unravel step by step 00:01:24.644 --> 00:01:26.294 what influences our DNA 00:01:26.294 --> 00:01:27.654 during our intere lifetime, 00:01:27.654 --> 00:01:28.884 our identity 00:01:28.884 --> 00:01:32.074 and, possibly, our inheritance. 00:01:33.389 --> 00:01:39.629 The new mysteries of our inheritance 00:01:40.044 --> 00:01:42.121 A film by Laurence Selfaty 00:01:42.121 --> 00:01:44.141 wrote together with Cécile Dumas
