There are two main differences between DNA and RNA: 1) RNA contains the sugar ribose while DNA contains deoxyribose, which lacks one oxygen atom. 2) RNA contains the nucleobase uracil while DNA contains thymine. DNA is double-stranded in a double helix structure, while RNA is usually single-stranded. The sugar in DNA is deoxyribose and RNA contains ribose. Furthermore, DNA uses the bases adenine, thymine, cytosine and guanine, while RNA uses adenine, uracil, cytosine and guanine.

3. THERE ARE TWO DIFFERENCES THAT DISTINGUISH DNA FROM
RNA: (A) RNA CONTAINS THE SUGAR RIBOSE, WHILE DNA
CONTAINS THE SLIGHTLY DIFFERENT SUGAR DEOXYRIBOSE (A
TYPE OF RIBOSE THAT LACKS ONE OXYGEN ATOM), AND (B)
RNA HAS THE NUCLEOBASE URACIL WHILE DNA CONTAINS
THYMINE.

4. DNA IS DOUBLE-STRANDED, FORMING A DOUBLE HELIX,
WHILE RNA IS USUALLY SINGLE-STRANDED. THE SUGAR IN
DNA IS DEOXYRIBOSE, WHEREAS RNA CONTAINS RIBOSE.
FURTHERMORE, DNA USES THE BASES ADENINE, THYMINE,
CYTOSINE, AND GUANINE, WHILE RNA USES ADENINE,
URACIL, CYTOSINE, AND GUANINE.
