    Extractions: Alfred Nobel was a Swedish chemist. He invented dynamite and became very rich. He gave more than 9 million dollars of his fortune to set up the Nobel prizes. Each year money from this fund goes to those who have most helped humanity. The Nobel Committee gives prizes for important work in physics, chemistry, medicine, literature, peace, and economics. Prize winners receive a cash prize (currently $1 million), a gold medal (above) and a certificate (below).

    Extractions: Alfred Nobel was a Swedish chemist. He invented dynamite and became very wealthy. When he died he left more than nine million dollars of his fortune to set up the Nobel prizes. According to his will, of 1895, the income from this fund was to be allotted each year in five equal parts as prizes to those who had most helped humanity. The interest from the money provides annual prizes for the greatest services to humanity in science and literature, and for the most effective work to promote friendship between nations (the Peace Prize). The Nobel prizes were first awarded on 10 December 1901, the fifth anniversary of Nobel's death. Nobel experimented a lot with nitroglycerine by itself and mixed with gunpowder. He patented detonating charges and percussion caps in 1864. He used these as a primary charge to trigger an explosion. Nobel later used a special clay from northern Germany to stabilise the nitroglycerine. When tested with a percussion cap, the preparation exploded evenly although with less power than nitroglycerine alone. He called this mixture of nitroglycerine and clay "dynamite". Nobel developed other explosive substances. Blasting gelatine, another powerful explosive, was a solution of gun cotton in nitroglycerine. Guncotton is a preparation of nitric acid and cellulose invented by Christian Schonbein in Germany in 1845. This evolved into modern dynamite which is a mixture of nitroglycerine and guncotton, with some additional ingredients.

Pøihlásil na tøistapadesát patentù ve všech státech svìta a málokdo se dožil uplatnìní svých vynálezù jako právì on. Jeho vynálezy byly výsledkem práce Nobelových laboratoøí v Nìmecku, Francii, Skotsku, Itálii a Švédsku. Své objevy realizoval v devadesáti továrnách a firmách dvaceti zemí pìti kontinentù. Pocházel z rodiny švédského chemika a podnikatele, ale rodina záhy odešla do Ruska, kde jeho otec díky vynálezùm protipìchotních a vodních min dosáhl velmi rychle váženého postavení. Alfred Nobel je znám pøedevším jako vynálezce smutnì proslaveného dynamitu (1867), ale obrovskou senzaci zpùsobil také jeho testament, který napsal na sklonku svého života 27. listopadu 1895 v Paøíži. Vyøízení pozùstalosti se protáhlo až do roku 1900, nebo nìkteøí zákonní dìdicové se snažili zpochybnit její platnost, a potíže nastaly také kvùli Nobelovu skuteènému bydlišti a váhavému postoji institucí, které mìly podle závìti pøevzít odpovìdnost pøi udílení penìžitých odmìn. Založení Nobelovy nadace a pøedpisy pro instituce oprávnìné udìlovat ceny schválil švédský král 29. èervna 1900 a první Nobelovy ceny byly udìleny již o rok pozdìji.

Sugar, inorganic salts, one vitamin (biotin) Spends most of life cycle in the haploid condition So recessive mutations will show up in its phenotype No need for test crosses Can be asexually propagated in large numbers by conidia (asexual spores) Can be mated to produce ordered tetrads Life cycle of Neurospora crassa Have two mating types (like sexes) A and a Matings occur only between two mycelia of differing mating types Can be crossed by placing two types of mycelia on the same plate Mycelia fuse, then nuclei fuse to form diploid zygote Diploid zygote undergoes two stages of meiosis, followed by one mitotic division These cell divisions occur in a narrow tube called the ascus (spore sac) Which causes the meiotic and mitotic products to remain in order (ordered tetrads) Thus, if the zygote nucleus is heterozygous for a gene (shown here as a and A) and there is no crossing over near that locus during meiosis I
