Let’s act it out!

• Find you partner base pair• Form a hydrogen bond!• Form two anti-parallel strands!

Your task for this period

Complete the DNA worksheet -read the text carefully and highlight the important points-answer the questions-colour in the diagram as instructed in the text

Can you label your DNA structure handout WITHOUT using your notes?

Now lets act it out again!

• Copy of DNA base stickers

• DNA helicase

• DNA polymerase

• Free nucleotides!

Your homework task:Design a stop-frame (with labels!) of DNA replication like this one

• It must include:- unwinding and unzipping by helicase-formation of new complementary strands by DNA polymerase

• You have until the 13th of November to complete this task

• It MUST be at least 1 minute long!

You may work in pairs, groups or individually.

Example of designing a stop frame• Use a digital camera/mobile phone to take a photo of every scene

• Upload the photos onto your computer

• Copy the images into a powerpoint presentation or Moviemaker

• Add labels using text boxes

• Rehearse your timings…

• Bring it to class on a USB next Tuesday!!

Now let’s extract some DNA!
