Yes, both DNA and RNA contain phosphodiester bonds in their backbone. These bonds form between the phosphate group of one nucleotide and the 3' hydroxyl (-OH) group of the sugar in the next nucleotide.
However, there is a slight difference due to their sugar components:
- In DNA, the sugar is deoxyribose (lacking an -OH at the 2' carbon).
- In RNA, the sugar is ribose (with an -OH at the 2' carbon).
Despite this, the phosphodiester bond structure is the same in both DNA and RNA, allowing them to form stable nucleotide chains.
