Examine the figure below. What would be the effect on
transcription if a mutation occurred in the gene that encodes GAL3,
so that no functional GAL3 was produced?
GAL4 UASG GAL80 In the absence of galactose, GAL80 blocks GAL4 from activating transcription. TATA Basal transcription apparatus Galactose GAL3 GAL80 GAL3 Galactose When galactose is present, it binds to GAL3 and brings about a change in the conformation of GAL80 GAL80 no longer binds to GAL4. GAL4 TATA 3 GAL4 can...

Describe how the expression of this gene is regulated. Include
the roles of all key players (GAL3, GAL4, GAL80, Gene promoter, RNA
polymerase, and transcription factors) illustrated.
Understanding regulation of transcription in eukaryotes. The images below depict how the expression of a gene required to break down lactose in yeast is regulated. The top image illustrates the key regulators of the process. The bottom two panels illustrate what happens in the presence and absence of galactose. Describe how the expression...

What would happen to the expression of this gene if this cell
did not have any GAL4 protein and why?
What would happen to the expression of this gene if this cell
did not have any GAL80 protein and why?

Question 3 1 pts What would happen to the expression of this gene if this cell did not have any GAL4 protein and why? It would be always off because GAL4 activates transcription . it would be always on because GAL80 won't be able to bind DNA without GAL4 it would be always on because GAL4 inhibits transcription it would only be on when galactose is present Question 4 1 pts What would happen to the expression of this gene...
Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dyst...
Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...
