Questions: DNA vs RNA Which pertains to DNA but not to RNA? Multiple Choice Contains nucleotides Contains uracil Contains ribose Contains thymine Contains adenine

The answer is the fourth one: Contains thymine.

Explanation for each option:

1. Contains nucleotides: This is incorrect because both DNA and RNA contain nucleotides.
2. Contains uracil: This is incorrect because uracil is found in RNA, not DNA.
3. Contains ribose: This is incorrect because ribose is the sugar found in RNA, whereas DNA contains deoxyribose.
4. Contains thymine: This is correct because thymine is a nitrogenous base found in DNA but not in RNA. In RNA, thymine is replaced by uracil.
5. Contains adenine: This is incorrect because adenine is found in both DNA and RNA.

Summary: The characteristic that pertains to DNA but not to RNA is that DNA contains thymine.
