Watch all three videos on DNA replication. Start with my lecture video. You will get a quiz on this content
This DNA replication Song was made by my students in 2007. They were grade 11 students taking my bio 12 course. Their music teacher is the same as your band teacher now.

Evaluation
Cartoon or poster or model with pipe cleaner /20
If you are using pipe cleaners use a pipe cleaner to represent one strand of DNA. Use an object to represent the enzymes involved. label these enzymes and photograph the steps of DNA repication. Put these photographs in a powerpoint presentation.
20 - This stands out in its effort and creativity
18-19. This is done in ink and colour and includes all the details above and the details are all correct. This is excellent
15-17. This is very good work with effort and correct details. Some details are not there but most are there and there is excellent quality of drawing and presentation.
