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′...

WebRNA from the DNA template. Relating to biology, explain the term 'reverse transcriptase'. Choose the best answer: DNA synthesis in all organisms occurs a. in the 5' to 3' direction. b. in the 3' to 5' direction. c. in the 5' to 3' direction on the leading strand but in the 3' to 5' direction on the lagging strand. d. WebDNA is read by DNA polymerase in the 3′ to 5′ direction, meaning the new strand is synthesized in the 5' to 3' direction. Since the leading and lagging strand templates are oriented in opposite directions at the replication fork, a major issue is how to achieve synthesis of new lagging strand DNA, whose direction of synthesis is opposite to the …
