There are two main differences between DNA and RNA with respect to structure. The first main difference deals with the base composition. DNA is composed of 4 nucleotides; adenine, guanine, cytosine and thymine. RNA is similar to DNA but contains uracil instead of thymine. The second main difference is with the sugar component of the ...
The key differences between DNA and RNA are discussed. The structure and function without taking supercoiling considerations are given.
