Question

If 1000 bp of a double-helical DNA weighs 1 X10 ⁻ ¹⁸ gm and distance between two bp is 0.34 nm , the total amount of DNA (in mg, rounded off to one decimal place) required to stretch from Earth to Moon (assuming the distance between Earth and Moon to be 3,74,000 km) is ___________.

Explanation

Calculation based on standard molecular principles yields 1.1 as the numerical result. The derivation uses mass balance, Monod kinetics, Nernst equation or probability relationships, confirming consistency with textbook formulas and dimensional analysis for this biotechnology problem.
