Summary- It has long been known that UV light can damage DNA, reducing its ability to replicate and interact with proteins, and often resulting in the development of skin cancers. However, not much is known about how the elasticity of DNA strands is altered upon exposure to UV light. Now a group of researchers at Duke University have developed a method to measure changes in the mechanical properties of DNA upon irradiation with UV light.

Questions-What are the major functions of nucleic acids in the cell? to tell the cell what to do
What are the differences in RNA and DNA? DNA contains Thymine, RNA contains Uracil
List three things you learned from this article in your own words. dna tell cell what to, UV light can damage dna, scientist can stretch dna while measuring the forces generated
What impact would the absence of this organelle have on the cell? cells would just float around in the body and be useless
