There are several changes that occur to pre-mRNA in eukaryotic cells to produce the final mRNA molecule that will be used in translation. This process is called RNA processing. Which of the following occurs in the process of producing this final mRNA molecule? a poly-A tail is added to the 5' end a modified guanine nucleotide is added to the 3' end the introns are cut out and the exons are attached to each other none of the above

Choose the best answer I) All of these events occur during the transcription in eukaryotes EXCEPT a) Messenger RNAs undergo extensive processing. b) A single mRNA codes for several proteins. c) Transcription and translation occur in separate cellular compartments. d) Unwinding from histones is probably necessary for transcriptional activation of the DNA. 2) Prokaryotic and eukaryotic promoters: a) contain AT-rich regions. b) interact with transcription factors. c) are influenced by base sequences thousands of base pairs away, which increase their...

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...
