In an experiment you add increasing amount of sigma factor to a mixture of DNA fragment and core polymerase in vitro. You also add ATP and 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?
The capacity of a band-limited additive white Gaussian noise (AWGN) channel is given by $$C = W\,{\log _2}\left( {1 + \frac{P}{{{\sigma ^2}W}}} \right)$$     bits per second (bps), where W is the channel bandwidth, P is the average power received and σ2 is the one-sided power spectral density of the AWGN. For a fixed $$\frac{P}{{{\sigma ^2}}} = 1000,$$   the channel capacity (in kbps) with infinite bandwidth (W → ∞) is approximately
