Model
4 pts

Model is accurate showing all essential components

Poor

Many components involved in protein synthesis are missing from the model or mis-named during the presentation. No understanding of the process or its components evident.
Fair

One or two components involved in protein synthesis are missing from the model or mis-named during the presentation. If the component moves in the process, it sometimes is movable in the model. The presentation of the model demonstrated a weak understanding of the process and its components. Hints are needed to elicit some correct answers about the processes occurring.
Good

All components are present in the model and correctly named during the presentation. If the component moves in the process, it also is movable in the model. The presentation of the model demonstrated a solid understanding of the process and its components. Most questions are answered correctly but some hints are needed to elicit some correct answers about the processes occurring.
Excellent

All components are present in the model and correctly named during the presentation. If the component moves in the process, it also is movable in the model. The presentation of the model demonstrated complete understanding of the process and its components, extra effort for clarity and detail are present, any questions are easily answered correctly without hints about the processes occurring.
Genetic Code
4 pts

At least three DNA triplet codes are properly transcribed into 2 mRNA codons

Poor

Codes are incorrectly transcribed or not shown. No understanding of the process or its components evident.
Fair

Only one code is transcribed correctly.
The presentation of this portion of the process demonstrated a weak understanding of the process and its components. Hints are needed to elicit some correct answers.
Good

Two or more codes are transcribed and labeled correctly. The presentation of this portion of the process demonstrated a solid understanding of the process and its components. Most questions are answered correctly but some hints are needed to elicit some correct answers.
Excellent

Two or more codes are transcribed and labeled correctly. The presentation of this portion of the process demonstrated complete understanding of the process and its components, extra effort for clarity and detail are present, any questions are easily answered correctly without hints.
Connections (one)
4 pts

At least three codon-anticodon combinations are properly labeled

Poor

Codon-anticodon combinations are not understood or missing. No understanding of the process or its components evident.
Fair

Only one or two codon-anticodon combination is shown correctly. The presentation of this portion of the process demonstrated a weak understanding of the process and its components. Hints are needed to elicit some correct answers.
Good

Three codon-anticodon combinations are shown correctly. The presentation of this portion of the process demonstrated a solid understanding of the process and its components. Most questions are answered correctly but some hints are needed to elicit some correct answers.
Excellent

Three or more codon-anticodon combinations are shown correctly with an extra effort for clarity and detail. The presentation of this portion of the process demonstrated complete understanding of the process and its components, extra effort for clarity and detail are present, any questions are easily answered correctly without hints.
Connection (two)
4 pts

At least three amino acids are linked by showing the beginnings of a protein (translation)

Poor

Connections between DNA or mRNA code and amino acids is not represented clearly or accurately. No understanding of the process or its components evident.
Fair

Only one or two amino acid is shown without any reference to peptide bonds. The presentation of this portion of the process demonstrated a weak understanding of the process and its components. Hints are needed to elicit some correct answers.
Good

Three amino acids are shown with one or more peptide bonds labeled between the amino acids. The presentation of this portion of the process demonstrated a solid understanding of the process and its components. Most questions are answered correctly but some hints are needed to elicit some correct answers.
Excellent

Three or more amino acids are shown with one or more peptide bonds clearly labeled between amino acids. A peptide chain is clearly represented. The presentation of this portion of the process demonstrated complete understanding of the process and its components, extra effort for clarity and detail are present, any questions are easily answered correctly without hints.
Correct coding
4 pts

All DNA, mRNA, tRNA and amino acids shall match proper triplet codes

Poor

Two or more of the codes shown (DNA-mRNA), (mRNA-tRNA), (mRNA translated to amino acid sequence) are incorrect
Fair

One of the codes shown is incorrect. Presenter is able to derive one or two novel codes upon questioning (codon to amino acid chart or table will be provided).
Good

All codes are accurate
Presenter is able to derive most novel codes upon questioning (codon to amino acid chart or table will be provided).
Excellent

All codes are accurate but drawing/model represented with extra clarity and detail
Presenter is able to derive any novel codes upon questioning (codon to amino acid chart or table will be provided).
