Document Summary
Nutritional mutants in neurospora: scientific inquiry a breakthrough in demonstrating the relationship between genes and enzymes came a few years later, where beadle and edward tatum began working with a bread mould, The products of gene expression: a developing story. Beadle and tatum"s idea was restated as the one gene-one polypeptide hypothesis. Genes provide the instructions for making specific proteins but does not build a protein directly. The bridge between dna and protein synthesis is the nucleic acid rna. An rna molecule usually consists of a single strand and has u instead of t as a base. In dna or rna, the monomers are the four types of nucleotides, which differ in their nitrogenous bases. Each polypeptide of a protein also has monomers arranged in a particular linear order (the protein"s primary structure), its monomers are amino acids. Transcription and translation occur in all organisms, both those that lack membrane bound nucleus and those that have one.
