L'ESPRESSIONE GENICA e il DOGMA della BIOLOGIA
🧬 LECTURE 54 of the Biology course with Giulia Gene expression consists of two stages: transcription and translation. There are two versions of the central dogma of biology, and the well-known one is not the original. 🔎 LET'S STUDY TOGETHER 📌 TIMESTAMPS ▶ 0:00 Introduction ▶ 0:39 Gene Expression ▶ 0:52 Transcription (DNA - RNA) ▶ 3:16 Translation (RNA - Protein) ▶ 4:51 Central Dogma of Biology: The First Version, by Crick, and the Second Version, by Watson ▶ 7:04 Retroviruses 📷 PHOTO SOURCE ▶ Photocopy: Photo by Mikhail Nilov: https://www.pexels.com/it-it/foto/man... ▶ Watson: By National Cancer Institute (NCI), Public Domain, https://commons.wikimedia.org/w/index... ▶ Crick: By Photo: Marc Lieberman - Siegel RM, Callaway EM: Francis Crick Legacy for Neuroscience: Between the α and the Ω.
