Hi Saswat, interesting point; but I do not think you can consider DNA width and pitch length as a reflection of fibonacci number. These are just two points, a fibonacci system has to reflect a bigger chunk of the series (like in pine cones, sunflower, spiral diving of birds like eagle). Besides, measuring in nm or pm, instead of A, will not conform to the fibonacci series. So, the consideration must be strictly "numerical" without any assistance of perceptible, changeable units. But I see it will be interesting to look deeper here!
