The true statement is: DNA has the sugar deoxyribose, while RNA has the sugar ribose.

The other statements are incorrect for the following reasons:

  • DNA is typically double-stranded, while RNA is usually single-stranded.
  • Thymine is only present in DNA, but cytosine is present in both DNA and RNA.
  • Transcription is the process of converting DNA to mRNA, while translation is the process of converting mRNA into proteins.
