What level of gene expression is affected by the mutations in fbxl3 and fbxl21 genes?
Transcription
Post-translational
Epigenetic
Splicing
Homework Answers
post-translational level.
( fbxl3 and fbxl21 are closest homologue and functionally antigonize each other. These have E3 ubiqitination and unubiquitination activity at protein level i.e. post-translational level.)

Both prokaryotes and eukaryotes regulate gene expression, turning genes on and off in response to various cues. Which of the following mechanisms is common to both types of cells? Choose all that apply. alternative splicing of mRNA opening or condensing chromatin transcriptional regulation post-translational regulation

How do transcription factors affect gene expression? a.) They are molecules that can turn genes on or off. b.) They are mRNAs that contain extra information that is not part of the DNA genome. c.)They modify the chromosome structure to create mutations. d.) They are signals that tell cells whether to divide or not.

Two genes (B and C) are transcription factors that affect the expression of gene A. The protein product of gene B allows gene A to be transcribed while the protein product of gene C doubles the rate of transcription of gene A. How does the expression of gene A differ between two individuals with the following genotypes? Assume lower case alleles produce non-functional proteins and each gene shows complete dominance. Individual 1: AA : BB : Cc Individual 2: AA...

Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...

Mutations in the exons of eukaryotic genes can result in changes in the translated protein. Nonexonic mutations, mutations in regions of a gene outside of the exons, can also alter the rate of transcription and the final protein. In which of the following situations would nonexonic mutations either affect expression of the gene or alter the structure of the final protein? Select all of the statements that apply.

In eukaryotic cells, there are specific transcription factors (activators) that regulate gene expression. Describe the organization of eukaryotic genes (i.e. promoters/enhancers) and how transcription factors are able to control gene expression and enzyme activity. a) Throughout the course we discussed the enzyme lactase and how it is differently regulated (and therefore expressed) in different human populations. Describe how this gene is differently expressed in different populations and when this/these change(s) are predicted to have taken place. b) Differential gene expression...
