The nucleic acid that contains the sugar deoxyribose is DNA (deoxyribonucleic acid). Among the options provided, neither "DNA helicase" nor "DNA polymerase" refers to the nucleic acid itself; they are both enzymes associated with DNA.
- DNA helicase is an enzyme that unwinds the DNA double helix during replication.
- DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain, using a template strand for guidance.
If you are looking for the nucleic acid itself, the answer is simply DNA. If you need a specific answer from the options given, based on their roles related to DNA, please clarify your question.
