Sinopse do Episódio "#04 | DNA – História da descoberta"
Na semana de aniversário do artigo na Nature do Watson e Crick que mudou o mundo, vamos conversar sobre os principais pesquisadores e eventos que levaram a descrição da molécula de DNA. Vamos falar de Mendel e os experimentos com as ervilhas, e de Rosalind Franklin que teve a famosa foto 51 mostrada sem autorização para o Watson e logo publicou a estrutura do DNA. E o modelo proposto por Linus Pauling, qual foi o principal erro?O Convidado desse quorum sensing é o Dr. Daniel Kumazawa do Instituto de Microbiologia da Academia de Ciência da República Tcheca.Se você ainda não segue o Podcast no instagram, procura lá por @animalculo.podcast - Sempre tem material extra.Lista Cronológica da história de descrição do DNA e artigos citados nesse episódio. •March 30, 1933: Note: "The Structure of Thymus Nucleic Acid."
