No, DNA and RNA do not have the same number of oxygen atoms. The key difference lies in their sugar components:
- DNA (Deoxyribonucleic Acid) contains deoxyribose, which lacks one oxygen atom at the 2' carbon of the sugar ring.
- RNA (Ribonucleic Acid) contains ribose, which has an extra hydroxyl (-OH) group at the 2' carbon.
This means RNA has one more oxygen atom per nucleotide than DNA. This difference affects their structure and stability—RNA is generally more reactive and less stable than DNA due to the additional oxygen.
