Galactose imported into the yeast cell is converted to galactose 6-phosphate by a pathway involving six enzymes, whose genes are scattered over three chromosomes. Transcription of these genes is regulated by the combined actions of the proteins Gal4p, Gal80p, and Gal3p,

i. GAL3	a. Interaction with the Gal80p-Gal4p complex and activates Gal4p.
ii. GAL4	b. Recruits SAGA, Mediator, and TFIID to the galactose promoters, leading to DNA polymerase II recruitment and initiation of transcription
iii. GAL80	c. Transcriptional inhibitor
	d. Transcriptional activator
