George beadle and edward tatum used mutant strains of neurospora to formulate the one-gene-one-enzyme hypothesis. researchers later updated this hypothesis to propose that one gene encodes one polypeptide because proteins can have multiple subunits. consider a heterotrimeric protein with all unique subunits. how many genes are required to form this protein?

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle
