Reference no: EM13651449

A 60 μm strand of DNA is strretched by an optical trapfrom equilibrium untill its ends are seperated by an additional 25μm. Assume that the spring constant k is approximatly10-10N/m.

A. What is the work done by the trap on the DNA strand?

B. How much force must the trap exert on the DNAstrand to maintain the 20-μm spacing.
