The eukaryotic subunit of RNA polymerase homologous to the ω subunit of bacterial RNA polymerase is ___________

Correct Answer: RPB6
The eukaryotic subunit of RNA polymerase homologous to the ω subunit of bacterial RNA polymerase is RPB6. RPA1, RPB2 and RPC5 subunits of eukaryotic RNA polymerase are homologous to the bacterial RNA polymerase subunits β’, β and αI respectively.

You design a reconstructive RNA polymerase where you take the beta and alpha subunit from a rifampicin resistant strain and beta prime and sigma subunit from rifampicin sensitive strain. You check the rate of transcription by this RNA polymerase after the addition of the antibiotic. What will be your observation?

What happens when the gp130 subunit and the leukemia inhibitory factor receptor β-subunit is combined with a ciliary neurotrophic factor’s receptor subunit?

Consider the following statements.
1. The smallest RNA is t RNA.
2. The most abundant RNA of cell is r RNA.
3. DNA can be formed over RNA through reverse transcriptase.
Which of the statements given above are false?

You isolate the nucleolus from the nucleus and performed a density gradient centrifugation with the extract. Then you check the different for the RNA polymerase activity of the different segment. Which RNA polymerase would you expect to find in abundance?

Consider the following statement
1. A bacterial food intoxication refers to food borne illnesses caused by the presence of a bacterial toxin formed in the food.
2. A bacterial food infection refers to food borne illnesses caused by the entrance of bacteria into the body through ingestion of contaminated foods and the reaction of the body to their presence or to their metabolites.
Which of the statements given above is/are correct?

Viral transduction is the process by which viruses carry bacterial DNA from one bacterial cell to another. In what way does this process play a role in bacterial evolution?

RPA 2 is one of the larger subunits of RNA polymerase in eukaryotes. It is homologous to the prokaryotic _____________

Eukaryotic RNA polymerase II does not directly bind to the promoter, but relies on a dozen or more transcription factors to recognize and bind to the promoter in a specific order before its own binding around the promoter.

How many of eukaryotic RNA polymerase subunits are common for all three polymerases?

The RNA polymerase core enzyme converts into a holoenzyme on the addition of the _________ subunit.
