Why is the DNA twisted and why is this shape helpful?
The DNA is a nucleic acid that is made of nitrogenous bases, deoxyribose sugars, and phosphate molecules. These molecules that make up the DNA interact with water and cause it to take a twisted shape. It is helpful in the packing of DNA into chromatin fibers. It also makes possible DNA replication and protein synthesis.
