GATE BT-2017 Answer Key | Solutions Discussion - CHANDA7 - 02-14-2017 Can anyone answer this question? At the transcription start site of a gene, any of the four nucleotides can occur with equal probability p. The Shannon Entropy S for this site would be?

Now, all we have to do is fill the same into the given equation: S= -[0.25*ln(0.25) + 0.25*ln(0.25) + 0.25*ln(0.25) + 0.25*ln (0.25)] = -0.25[4ln(0.25)] =-1*ln(0.25) =-ln(0.25) =-ln(1/4) =-[ln(1) - ln(4)] = -[0 - ln (2*2)] = ln(2) +ln (2) =0.69 + 0.69 = 1.38 I hope this is the way to go about it...

Other students will be searching for answers by typing some lines of the question and therefore it is important to post the queries in a 'search friendly way'. Hope the point will be acknowledged...thanks and best wishes..
