Describe the structural differences between DNA and RNA.

DNA is a double helical structure. It is a long polymer molecule which has deoxyribose sugar and phosphate backbone. It have four nitrogenous bases which are supported by the phosphate backbone. These are the adenine, guanine, thymine and cytosine.

RNA is a single stranded molecule. It is a polymer with a ribose sugar and phosphate backbone. It also exhibit four nitrogenous bases that are supported by phosphate backbone these are adenine, guanine, cytosine and uracil.
