Fill in the table below to differentiate the process of transcription between prokaryotes and eukaryotes.
Consider gene expression in a prokaryotic or bacterial cell. Which of the following is true for transcription in this cell? Select all that apply. During Transcription, the enzyme topoisomerase relaxes negative supercoiling in the DNA strands MRNA can be synthesized by Transcription and at the same time this mRNA can be used for protein synthesis or Translation MRNA has to be processed before leaving the nucleus RNA polymerase requires sigma factor for efficient transcription initiation
Alternative splicing happens in both pro- and eukaryotes. True O False The yeast Gal80 protein inhibits transcription, but by binding to a transcriptional activator protein instead of to an operator. True O False
A bacterial species has a hypothetical sigma promoter that has the following sequence: TTGGCA - 18 bases - TATAAT What change in the level of transcription would there be if the sequence was mutated to: TTCGCA -18 bases -TATAAT O The mutation would bind the promoter to the consensus and produce normal levels of transcription O The mutation would inhibit the promoter thereby inhibiting transcription The mutation would move the promoter away from consensus and reduce the level of transcription O No change the consensus TATAAT sequence in the same.

Editing during DNA replication is provided by DNA polymerase enzymatic activity of O 5'-> 3' polymerase 3'-> 5' polymerase O 3'-> 5' exonuclease O an extra enzyme that binds to DNA polymerase O 5'-> 3'exonuclease
Lack of phosporylation of the C-terminal domian of Pol Il will result in which of the following? O Assembly of the full set of general transcription factors plus Pol II at the promoter, but unphosphorylated Pol II cannot leave the promoter region No assembly of the general transcription factors at a promoter No binding of Pol II at a promoter The unphosphorylated Pol II can initiate and elongate but cannot terminate
Which of the following statements is false? a mutation in a 5' or 3' splice site must alter the sequence of the protein encoded by a gene a missense mutations replaces one amino acid with a different amino acid a mutation in a promoter is unlikely to alter the sequence of the polypeptide encoded by a gene a mutation in a transcriptional terminator is unlikely to alter the sequence of a protein encoded by a gene. a frameshift mutation changes the sequence of a protein 0000
Why do promoter mutations cluster at positions −10and −35 as shown in Figure 11-11? Which protein-DNAinteraction is disrupted by these mutations?
Suppose you had isolated a new transcription factor and wanted to know which genes this protein might regulate. Is there any way that you could use a cDNA microarray of the type shown in the picture to approach this question?
Which of the following statements is false? a mutation in a 5' or 3' splice site must alter the sequence of the protein encoded by a gene a mutation in a transcriptional terminator is unlikely to alter the sequence of a protein encoded by a gene. a mutation in a promoter is unlikely to alter the sequence of the polypeptide encoded by a gene a missense mutations replaces one amino acid with a different amino acid a frameshift mutation changes the sequence of a protein 000 0
In eukaryotic transcription, which of the following is not included in the initiation of transcription? Group of answer choices RNA polymerase II TATA box Holoenzyme AAUAAA consensus sequence
The diagram, shown in attatched image, shows an mRNA that is alternatively spliced. The alternatively spliced variant contains Exon 1, Exon 2, and Exon 4. Indicate below if a splice site is used, blocked by a modifying protein such that the spliceosome must choose a different site, or skipped to make this alternatively spliced variant.
