Complete the table to compare DNA and RNA.or both

contains the 5-carbon sugar ribose


is typically a single-stranded molecule


contains the 5-carbon sugar deoxyribose


is typically a double-stranded molecule

Answer 1

- contains the 5-carbon sugar ribose — RNA
- is typically a single-stranded molecule — RNA
- contains the 5-carbon sugar deoxyribose — DNA
- is typically a double-stranded molecule — DNA

(Note: there are exceptions — some viruses have ssDNA or dsRNA, and RNA often forms internal double-stranded regions.)
