Although they are almost identical, there are three major differences

1.) RNA is single stranded while DNA has a double helix

2.) RNA has uracil while DNA has thymine

3.) RNA has a ribose base while DNA has a deoxyribose base

Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
