WebStages in which the lagging strand is synthesized: 1. DNA polymerase begins synthesizing the lagging strand by adding nucleotides to a short segment of RNA. 2. After each strand of the lagging strand is complete, it is released from the DNA polymerase. 3. A different DNA polymerase replaces the RNA segments with DNA. 4. WebSep 27, 2024 · The lagging strand is replicated in segments known as Okazaki fragments. The gaps between the Okazaki fragments are filled in by the enzyme DNA ligase. The process of DNA replication is tightly regulated to ensure accuracy and prevent errors. 11 mutations are changes in the DNA sequence that can affect the genetic code. impul s13 headlights

WebOH bonds must be broken between the two strands of DNA. RNA primase constructs a short RNA primer. DNA ligase forms a phosphodiester bond between the 3' OH of the growing strand and the 5' phosphate in front of it. DNA polymerase I removes some material and replaces it with DNA. DNA polymerase III adds deoxyribonucleotides. WebJul 30, 2024 · Major Enzymes. The process of DNA replication is catalyzed by a type of enzyme called DNA polymerase (poly meaning many, mer meaning pieces, and –ase meaning enzyme; so an enzyme that attaches many pieces of DNA).
