The theme is the investigation of the chemical structure of the baleen hair strands.\u003c\/p\u003e\n\u003cp\u003eThe author, through several chemical decompositions (in alcohol, ether, acetic acid, sulphuric acid, etc.) and analysing the results under the microscope (with a 233x zoom), manages to verify, by means of luminescence, the existence of nucleic acids proper to the whale, by comparison with the structure of other vegetal matters. This is a scientific step towards the knowledge of DNA at the beginning of the 20th century.\u003c\/p\u003e\n\u003cp\u003eÂ \u003c\/p\u003e","brand":"Garimpo dos Livros","offers":[{"title":"Default Title","offer_id":58295804592460,"sku":"1604NM040","price":9000.0,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5617\/0316\/files\/1604NM040_1.jpg?v=1785850998","url":"https:\/\/garimpodoslivros.com.br\/products\/dissertatio-chemica-inauguralis-de-balaena","provider":"Garimpo dos Livros","version":"1.0","type":"link"}
