DNA Replication Unit

Centered around the essential question, “How does DNA make an exact copy of itself before a cell divides?”, this unit walks students through the entire process of DNA replication in a way that’s clear, approachable, and engaging. Through engaging instruction, visual explanations, and interactive activities, your class will gain a solid understanding of how this critical process works—without feeling overwhelmed by the complexity.

Why Teachers Love This Resource:

• Breaks down the steps of DNA replication in a way students actually understand
• Makes tricky enzyme names and functions stick through repetition, visuals, and hands-on practice
• Gives students voice and choice with a flexible writing assignment they can connect to
• Includes everything you need to teach this mini-unit—no extra prep required

What’s Inside:

• Unit Pacing Guide – A clear 3-day layout with a central question and built-in review time to keep learning on track.
• Detailed Lesson Plan – Outlines goals, background knowledge, materials, and step-by-step instructions for each day.
• DNA Replication Presentation & Notes – This guided slide presentation explains each step of replication and the role of key enzymes.
  Heads up: It’s a bit longer than typical lessons, so feel free to split it over two class periods depending on your schedule or student needs.
• DNA Homework Assignment – Students pick from a few prompt options and write a two-paragraph response. It’s a great way for them to process what they’ve learned in their own words.
• Cut & Paste Sequencing Activity – A fun and effective way for students to review replication steps by physically putting them in the correct order.
• DNA Replication Quiz – Covers replication steps, enzyme functions, and accuracy in DNA copying.
• Answer Keys – Every activity and the quiz comes with a full key to make your grading quick and easy.

Pro Tip: Use real-world analogies—like recipe copying or computer file duplication—to help students visualize how replication works and why accuracy matters. Bonus: These comparisons make excellent class discussion starters or exit tickets!
