Scientists seeking to determine which molecule is responsible for the transmission of characteristics from one generation to the next knew that the molecules must (1) copy itself precisely (2) be stable but able to be changed and (3) be complex enough to determine the organism’s phenotype. a. explain how dna meets each of the three criteria stated above. b. select one of the criteria stated above and describe experimental evidence used to determine that dna is the hereditary material.

Which of the following statements regarding anfinsen's denaturing experiments with ribonuclease a (rnase a) are valid? exposing the denatured protein to air oxidation and then dialysis to remove urea restored the protein to its original functionality. removing urea by dialysis and then allowing air oxidation of the denatured protein restored the protein to its original functionality. denaturing the protein with both urea and β-mercaptoethanol yielded an inactive protein. anfinsen concluded that protein folding is determined by its primary sequence.

If assuming tasting ptc as a simple gene trait, what other genotype would you select to put in this missing genotype box that could result in this phenotype
