La DOPPIA ELICA del DNA - Erwin Chargaff, Rosalind Franklin, James Watson e Francis Crick

🧬 LECTURE 50 of the Biology course with Giulia DNA has a double helix structure, and we can imagine it as a spiral ladder. 🔎 LET'S STUDY TOGETHER 📌 TIMESTAMPS ▶ 0:00 Introduction ▶ 0:49 Erwin Chargaff - Chargaff's Rules ▶ 4:23 Rosalind Franklin (and Maurice Wilkins) - Photo 51 ▶ 6:11 The Story of a Discovery and a Missed Nobel Prize ▶ 7:36 The Double Helix Model of DNA (Let's Use a Model) ▶ 9:12 The Two DNA Strands Are Antiparallel (5' - 3') ▶ 10:37 Complementary Base Pairing 📷 PHOTO SOURCE ▶ The DNA structure model used in the video is "DNA Double Helix Structure Model" by 3B Scientific. ▶ Erwin Chargaff: Photo courtesy of the National Library of Medicine. ▶ Rosalind Franklin: MRC Laboratory of Molecular Biology, CC BY-SA 4.0 https://creativecommons.org/licenses/..., via Wikimedia Commons ▶ Photo 51: Flickr - Rosenfeld Media ▶ Experiment Photo 51: Edited by MagentaGreen, CC BY-SA 2.0 https://creativecommons.org/licenses/..., via Wikimedia Commons ▶ Watson and Crick: Flickr - Rosenfeld Media ▶DNA Structure: The original uploader was Mstroeck at English Wikipedia., CC BY-SA 3.0 http://creativecommons.org/licenses/b..., via Wikimedia Commons 🧲 RECOVER USEFUL LESSONS ▶ Atoms:    • GLI ATOMI - protoni, neutroni, elettroni, ...   ▶ Water and Hydrogen Bonds:    • L'ACQUA E I LEGAMI A IDROGENO - le caratte...   ▶ Proteins - The 20 Common Amino Acids:    • LE PROTEINE - i 20 amminoacidi comuni   ▶ Nucleic Acids and Nucleotides:    • ACIDI NUCLEICI e NUCLEOTIDI   ▶ The Nucleus - The Home of Genetic Material:    • Il NUCLEO - la sede del materiale genetico   ▶ DNA is the hereditary material!
