Q1. During DNA replication, a new nucleotide is added to a growing strand. Which specific carbon positions are involved in forming the phosphodiester linkage?
Answer: 5' phosphate and 3' hydroxyl
Explanation: The bond forms between the 5' phosphate of the new nucleotide and the 3' hydroxyl of the existing chain. Glycosidic bonds link sugars to bases.
