DNA Replication Students will model DNA and show the steps of DNA replication
	Level 1 1 pts	Level 2 2 pts	Level 3 3 pts	Level 4 4 pts
Model 4 pts Drawing/model is accurate showing all essential components (sugar/phosphate backbone, all enzymes, replication fork, double helix etc)	Level 1 Many components of DNA are missing or not labeled and base pairs are not correctly matching.	Level 2 One or two components involved in making DNA are missing or mislabeled	Level 3 All components are labeled properly	Level 4 All components are labeled properly and show an extra effort for clarity and detail and ALL bases are labeled. Model is showing the double helix. Base pairs are correct.
First step of DNA replication 4 pts Shows DNA unzipping	Level 1 Does not show DNA unzipping	Level 2 DNA unzipped and not labeled	Level 3 DNA unzipped but partially labeled (not all bases labeled)	Level 4 DNA is shown unzipped with bases labeled with correct letter
3 phases 4 pts The three phases are demonstrated with words and pictures	Level 1 Does not show all phases of DNA replication.	Level 2 Shows 2 phases, using words and pictures.	Level 3 Shows 3 phases of the replication process but it is not explained.	Level 4 All phases are demonstrated wih diagrams and clearly explained with words.
Two molecules of DNA 4 pts Shows two identical copies of DNA	Level 1 Does not show two new molecules of identical DNA strands.	Level 2 Two molecules of DNA that are identical to the original DNA but is not in a twisted ladder format and is not labeled.	Level 3 Two molecules of DNA that are identical to the original DNA but is not in a twisted ladder format and is labeled.	Level 4 Two molecules of DNA that are identical to the original DNA. It is completely labeled (bases labeled correctly) and is in a twisted ladder format.
