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?
Homework Answers
Galactose binds to GAL3 protein. Then GAL3 is found in activated form. It will interact with GAL80 and there are not found interaction of GAL 80 with the DNA. Hence the transcription will not occur.
-------
Answer)
When GAL3 protein is non functional in nature, then GAL3 protein can not bind to the galactose. Hence GAL 3 can not bind to the GAL80 protein. GAL80 protein remains bind with the DNA. Hence it will repress the transcription process. Because GAL 4 can not bind to the promoter.

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 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...
