Answer 1

The correct response is:

DNA contains thymine, while RNA contains uracil.

This statement accurately reflects a key difference between DNA and RNA. DNA has the nitrogenous base thymine (T), whereas RNA has uracil (U) instead of thymine.

The other options contain inaccuracies about the structures and locations of DNA and RNA.
