Identify which eukaryotic level of gene regulation is most applicable in the given examples. (Pre-transcriptional control, Transcriptional control, Translational control, Post-translational control) The glycolytic enzyme pyruvate kinase is activated by dephosphorylation and inactivated by phosphorylation. In the fruit fly, genes for rRNA can be replicated more or less often compared to the rest of the chromatin depending on the needs of the cell. In the human beta-globin, two introns are spliced out in order to produce the mature mRNA. DNA methylation can change the degree of condensation of the chromatin.
a. Show (on the image) 3 steps that must be taken to produce a mature mRNA molecule from this pre- mRNAb. Place an arrow at the 5’ end of intron 2. (splice site). c. Why is a promoter not shown in this image?
The diagram below shows the structure of DNA from the level of a gene to a condensed mitotic chromosome. At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.
