What are the main differences between DNA and RNA? (Select all that apply)
DNA contains deoxyribose, RNA contains ribose.
DNA is typically double-stranded, RNA is typically single-stranded.
DNA contains uracil, RNA contains thymine.
DNA is present in the nucleus; RNA is present in the cytoplasm.
Explanation
The main differences are in their sugar (deoxyribose vs. ribose) and structure (double vs single). DNA has thymine, and RNA has uracil. DNA is usually only in the nucleus.
