Question

How does the structure of DNA differ from the structure of RNA?

Answer 1

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

Answer 2

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.
