Master DNA Replication fast ⚡ – clear explanations, supportive visuals, OCR-aligned.
You’ll cover
• How DNA is synthesised from nucleotides during replication.
• The role of enzymes involved in DNA replication, including DNA helicase, DNA polymerase, primase and DNA ligase.
• Directionality of DNA synthesis and why replication proceeds in the 5′→3′ direction.
• The differences between leading and lagging strand synthesis, including Okazaki fragments.
• How complementary base pairing and proofreading ensure accuracy.
• What semi-conservative replication means.
What’s included
• Detailed, labelled diagrams showing the DNA replication fork and enzyme action.
• Step-by-step visual sequences of leading and lagging strand synthesis.
• Clear diagrams illustrating Okazaki fragment formation and joining.
• Visual breakdown of enzyme roles at each stage of replication.
• Tables summarising mechanisms that reduce mutation risk during replication.
• Concise spec reminders embedded alongside diagrams to reinforce key OCR wording and expectations.
