Question

The MAT locus allows yeast to switch mating type through a very complex mechanism. However, it has informed us a great deal about what aspects of gene expression typical to all organisms?

Options:

	higher order changes in chromatin affect transcriptional efficiency
	that general transcription factors must first bind directly to histone tails and only then can they interact with their cognate binding sites
	that DNA methylation is involved in this silencing mechanism
	that SIR2 is required for all types of transcriptional repression
	that expression of Pol III genes provides a means of identifying active chromatin
