1.Gal4 is involved in the regulation of galactose metabolism

a.Describe how transcription would be affected in the presence of the following mutations.

i.A mutation that resulted in an inability of Gal80 to enter the nucleus.

ii.A mutation that resulted in a lack of ability of Gal3 to bind galactose.

iii.A mutation that resulted in Gal4 being unable to bind the UAS_G.

Solution

A mutation that resulted in an inability of Gal80 to enter the nucleus:

A mutation that resulted in a lack of ability of Gal3 to bind galactose.

A mutation that resulted in Gal4 being unable to bind the UASG.
