Mating Ste12 Tec1 Budding 17. (8 points) Scientists are studying the transcription factors Ste12 and Tec1. They have found that when ste12 binds to one part of the genome alone it activates the transcription of genes important in mating pheromones. They also found that when Tec1 binds to another part of the genome alone it activates the transcription of cellular budding genes. Lastly, they found that in another part of the genome, Ste12 and Tec1 both bind to the DNA, they activate the transcription of genes that control the formation of filaments. a) These proteins bind to enhancers. Is Ste12 and Tec1 activators or mediators? How do you know? Filamentation b) Is this system an example of combinatorial control or coordinated control, both or neither? Explain your answer. sold ad bosow
