Researchers who initially investigated the cell cycle needed to identify the key proteins involved. They employed genetic screens using yeast as their model organism to search for mutants which cannot transit the cell cycle. a. Mutants which cannot transit the cell cycle cannot grow, so what strategy did the researchers use to identify the genes responsible? Briefly, explain how this strategy works. (3 marks) b. Explain how "rescue" experiments in yeast could be used to identify the human homologues of yeast cell cycle genes. (2 marks)
