Question: Phosphodiester bond forms between which of the following?
Options:
2'C and 1'C
5'C and 3'C
5'C and 2'C
3'C and 1'C
✅Explanation:
-In nucleotides, which are the building blocks of nucleic acids like DNA and RNA, a phosphodiester bond forms between the 3' carbon of the pentose sugar (ribose in RNA, deoxyribose in DNA) of one nucleotide and the 5' carbon of the pentose sugar of the next nucleotide. This linkage creates a sugar-phosphate backbone that forms the structure of the nucleic acid strand.
