one gene-one enzyme hypothesis - each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? - Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) - Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials into amino acids and vitamins needed for gro...

The anticodon on the tRNA for alanine is CGU and the anticodon for threonine is UGU. What is the base change that resulted in the SLC245A mutation? correct answers - cytosine to thymine The codons for arginine include CGA, CGC, CGG and CGU. what is the base change in the anticodon that results in the amino acid switch from the ancestral African form to the East Asian pattern of pigmentation from this mutation in the OCA2 gene? correct answers - uracil to cytosine from the passage, which of...
