A) DNA encodes hereditary information, whereas RNA does not.
B) The bases in DNA contain sugars, whereas the bases in RNA do not contain sugar.
C) DNA nucleotides contain a different sugar than RNA nucleotides.
D) DNA contains the base uracil, whereas RNA contains the base thymine.
E) The bases in DNA contain sulfur, whereas the bases in RNA do not contain sulfur.

Question

Quizplus · Accepted Answer

The main difference between DNA and RNA is that the sugar molecule in DNA is deoxyribose, while in RNA it is ribose. This means that DNA nucleotides contain a different sugar than RNA nucleotides. The other options are incorrect: A is incorrect because RNA also carries genetic information; B is incorrect because the bases in RNA do indeed contain sugar; D is incorrect because DNA contains thymine, whereas RNA contains uracil; E is incorrect because neither DNA nor RNA contains sulfur in their bases.
