In a Drosophila polytene chromosome just before molting you add green labelled antibody against unphosphhorylated RNA pol II CTD and red labelled antibody against phosphorylated RNA pol II CTD. These give fluorescence on adding the respective substrates. What will be the colour in gene 74 EF and 75 B?
While in vitro transcription your RNA pol is stalled at a position due to mistreatment. Which factor could you act to help the RNA pol overcome the stalled stage?
In an experiment, you are trying to pull down the site where guanyl transferase binds by co-immunoprecipitation. You run a gel and autoradiograph to see a band denoting GSK-RNA pol II (phosphorylated). What will you see when you perform the same experiment with overexpression of GSK in one setup and overexpression of unlabelled GSK-RNA pol II in the other setup?
The pre-rRNA transcript transcribed by the RNA pol Idoesn’t include_________
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 want to find out which of the consequent gene X or Y is being transcribed. For this you do a hybridization competition analysis and plot the radioactivity curve with increasing concentration of the competitor unlabelled mRNA. If the transcribed gene was X, which observation fits your result?
You transcribe a gene and obtain mRNA. To detect which strand is transcribed you replicate each strand in vitro and use the newly synthesized strand for hybridization with mRNA. If mRNA hybridize with the newly replicated strand from 1st strand then the gene transcribed was in ________
