  Poor

Fair

10 pts

Good

15 pts

Excellent

20 pts

Model
20 pts

Model is accurate showing all essential components (sugar/phosphate backbone, all 4 bases, double helix, tRNA, mRNA, Amino Acids, ribosomes, polymerase, helicase, etc.))
Poor

Many components of DNA are missing or not labeled and base pairs are not correctly matching.
Fair

One or two components involved in making DNA are missing or mislabeled
Good

All components are labeled properly
Excellent

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
20 pts

Shows how DNA is unzipped (including all necessary components)
Poor

Does not show DNA unzipping
Fair

DNA unzipped and not labeled
Good

DNA unzipped but partially labeled (not all bases labeled)
Excellent

DNA is shown unzipped with bases labeled with correct letter
New halves of DNA built
20 pts

Shows that nucleotides are used to build other halves of DNA
Poor

Does not show new halves of DNA being built.
Fair

Shows something being built, but model is unclear
Good

Correct nucleotides used to build other halves of DNA but not labeled.
Excellent

Correct nucleotides used and labeled to build other (new) halves of DNA
Two molecules of DNA
20 pts

Shows two identical copies of DNA
Poor

Does not show two new molecules of identical DNA strands.
Fair

Two molecules of DNA that are identical to the original DNA but is not in a twisted ladder format and is not labeled.
Good

Two molecules of DNA that are identical to the original DNA but is not in a twisted ladder format and is labeled.
Excellent

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.
Why DNA needs to copy
20 pts

Explains the purpose of DNA replication and what could go wrong if there are mistakes (mutations).
Poor

Does not give an explanation as to the purpose of DNA replication and does not give examples of genetic mutations.
Fair

Gives an explanation of the purpose of DNA replication but does not give examples of genetic mutations.
Good

Explains thoroughly the purpose of DNA replication and gives general examples of genetic mutations.
Excellent

Explains thoroughly the purpose of DNA replication and gives SPECIFIC examples of what could happen if there is a mutation in reproductive cells that could have an effect on offspring.
