Show Answers

DNA contains thymine while RNA contains uracil.DNA has deoxyribose sugar and thymine, whereas RNA contains ribose sugar and uracil.DNA includes ribose and thymine, but RNA has deoxyribose and uracil.DNA features deoxyribose sugar, and RNA contains ribose sugar.DNA and RNA differ only in their nitrogenous bases.

Explanation

DNA and RNA differ chemically primarily in their sugar components and nitrogenous bases. DNA contains deoxyribose sugar and the base thymine, while RNA contains ribose sugar and uracil instead of thymine.
