Textbook Question
Chapter 4, Problem 3AQ
What would be the result (in terms of protein synthesis) if RNA polymerase initiated transcription one base upstream of its normal starting point? Why? By inspecting Table 4.4, discuss how the genetic code has evolved to help minimize the impact of mutations.

What happens when one base pair of DNA is lost from the coding region of a gene because of mutation? First explain how this would affect the mRNA sequence, and second, explain how this would alter the amino acid of the protein that is encoded.
Why is it important for a transcription factor/activator to have a high affinity for a specific DNA sequence?
If a mutation occurred in the pRM promoter that rendered this promoter as ‘nonfunctional and unable to allow for transcription to occur’, what would be the outcome?

In eukaryotes, transcription occurs simultaneously with translation, while transcription in prokaryotes must complete before translation can begin. In eukaryotes, transcription is completed by an RNA polymerase, while transcription in prokaryotes is completed with a DNA polymerase. In eukaryotes, transcription produces an RNA molecule, while transcription in prokaryotes produces a DNA molecule. In eukaryotes, transcription produces a monocistronic RNA, while transcription in prokaryotes produces a polycistronic RNA. In eukaryotes, transcription produces an DNA molecule, while transcription in prokaryotes produces a RNA molecule.arrow_forward
