Dna has an extra phosphate on the backbone
Web* The DNA double helix is constructed from two strands of DNA, each with a sugar-phosphate backbone and nitrogenous bases that form hydrogen bonds, holding the two strands together. Each DNA strand has two unique ends. The 3' end has a hydroxyl (-OH) group on the deoxyribose sugar, whereas the 5' end has a phosphate group. WebDNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3' end of a growing DNA strand. DNA polymerase is the enzyme complex responsible for synthesizing a new strand of DNA, using an existing strand as a template. A hydroxyl is present at the 3' end of the growing DNA strand. What is at the 5' end? A phosphate …
