The true statement is:

DNA has the sugar deoxyribose, while RNA has the sugar ribose.

The other statements are incorrect:

  • DNA is double-stranded, while RNA is typically single-stranded.
  • Transcription copies DNA to mRNA, while translation converts mRNA into proteins, so the first part of that statement is incorrect.
  • Thymine is only present in DNA, while uracil (not cytosine) is present in RNA.
