Central Dogma of Biology Students will model the steps in the process from DNA to protein synthesis
	Level 1 1 pts	Level 2 3 pts	Level 3 4 pts	Level 4 5 pts
Genetic material 5 pts DNA structure, location, and functions	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 DNA are missing or mislabeled. No description, or is incorrect.	Level 3 All components are labeled properly. Some important vocabulary is present in description.	Level 4 All components labeled properly.Clarity in detail and bases are labeled. Model of the forked double helix. All biochemicals are correct. Description includes appropriate vocabulary.
Transcription 5 pts mRNA is made from DNA code, location, functions	Level 1 Does not show single strand of RNA being made from DNA (unzipped)	Level 2 mRNA just appears without DNA replication being shown	Level 3 DNA unzipped but partially labeled (not all biochemicals labeled). mRNA partially labeled.	Level 4 DNA is shown unzipped with biochemicals labeled correctly, mRNA biochemicals also correctly labeled.
mRNA to ribosome 5 pts cellular pathway from DNA to protien	Level 1 No picture or mention of mRNA at ribosome. No mention of translation, or not explained at all.	Level 2 mRNA shown at ribosome, little support with written word to explain translation process. Amino acids and/or tRNA missing from drawing.	Level 3 Translation process depicted accurately, but missing some details.	Level 4 mRNA, ribosome, base pairs being translated into amino acids. tRNA w/ specific amino acid to match anti-codon, which matches codon on mRNA. Written explanation to support visuals. All biochemicals correct for amino acids.
Translation 5 pts polypeptide chain is formed using m, r, and tRNA, locations, functions	Level 1 No polypeptide chain shown.	Level 2 Unidentified amino acids in polypeptide chain, no depiction or mention of tRNA.	Level 3 At least one amino acid is identified. Peptide bonds labeled, tRNA depicted or described.	Level 4 Polypeptide chain with correct amino acids for the N bases of mRNA. More than one tRNA shown and all correct.
Illustrations 5 pts label structures, functions, flow	Level 1 One illustration, not labeled correctly, does not pertain to process.	Level 2 Only 1 illustration, some factors detailed, correctly labeled.	Level 3 Two correctly detailed illustrations depicting steps in the process	Level 4 More than 2 correctly detailed illustrations depicting steps in the process in the correct order.
