In an experiment, you wanted to see which mutation will have worse effect on transcription. In the 1st set you deleted 94 amino acids from the C-terminus and in the 2nd set you replace the 265th C-terminal arginine to cystine. Which in your opinion will have the worst effect?
In an experiment you add increasing amount of sigma factor to a mixture of DNA fragment and core polymerase in vitro. You also add [14C]ATP and [γ-32P]ATP in the mixture and check the rate of incorporation. Results show that the incorporation of both of this labels increase on adding more sigma factor. What will you conclude from your observation?
Mutations as far as 100 base pairs upstream to +1 site will also affect the transcription rate.
