Web21 mrt. 2024 · Figure 19.3. 1: A Schematic Diagram of DNA Replication. DNA replication occurs by the sequential unzipping of segments of the double helix. Each new nucleotide is brought into position by DNA polymerase and is added to the growing strand by the formation of a phosphate ester bond. Thus, two double helixes form from one, and each … WebAnswer: Thanks for the A2A! DNA polymerase produces loops in the DNA, called Okazaki fragments because the polymerase can only synthesize DNA in the 5′ to 3′ direction and the lagging strand runs in the 3′ to 5′ direction. This allows the polymerase to synthesize short segments of DNA in the 5′...

Why DNA polymerase can only work from 5
Web6 jul. 2024 · 2.2) Why does DNA synthesis only proceed in the 5’ to 3’ direction? Because DNA polymerase can only add nucleotides to the 3´ end of the polynucleotide strand. Because the 3´ end of the polynucleotide molecule is more electronegative that the 5´ end. Because that is the direction in which the two strands of DNA unzip. WebGood notes see discussions, stats, and author profiles for this publication at: general microbiology, concise notes book november 2016 citations reads 68,452 Web5 jan. 2012 · DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides.
