http://cyberbridge.mcb.harvard.edu/dna_1.html WebJan 8, 2024 · An enzyme that creates a phosphodiester bond between the 3’ end of one DNA segment and the 5’ end of another. Once the RNA primer has been removed and replaced the adjacent Okazaki fragments must be linked together. The 3’-OH end of one fragment is adjacent to the 5’-Phosphate end of the previous fragment.
WebDuring strand elongation, two phosphates are cleaved from the incoming nucleotide triphosphate and the resulting nucleotide monophosphate is added to the DNA strand. This results in the: Formation of a phosphodiester bond between the phosphate attached to the 5' carbon of the incoming nucleotide and the hydroxyl group on the trailing 3' carbon WebAug 15, 2024 · Phosphodiester Bonds. Oh, um, did I forget to tell you what a polynucleotide is? A polynucleotide is simply a long chain of nucleotides. 'Poly-' means 'many', so 'polynucleotide' literally means ...
WebPhosphodiester bonds in DNA polymers connect the 5’ carbon of one nucleotide to the 3’ carbon of another nucleotide The nucleotide monomers in a DNA polymer are connected by strong electromagnetic attractions called phosphodiester bonds .
