Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...

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...

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

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...
