Outline of DNA to Trait Projects

These are adapted from the shared document Outline of DNA to Trait Projects, April 2011.

DNA to Trait 1: colorless

Students discover the molecular basis of colorless based on learning about an enzyme deficiency in Frost drakes.

Go to the colorless demo.

DNA to Trait 2: Metallic

Students discover that molecular basis of Metallic based on information in an old study of the phenotype, done long before the genome sequence was available.

Go to the Metallic demo.

DNA to Trait 3: Bog breath

Students discover the molecular basis of bog breath and dancer by learning about the urea cycle.

Go to the bog breath demo.

DNA to Trait 4: brown

Students discover the molecular basis of brown following a mapping experiment.

Go to the brown demo.

DNA to Trait 5: dilute

Students discover the molecular basis of dilute following a mapping experiment.

Go to the dilute demo.


These are meant to be interesting challenges. There is a useful table on the help page.

If you are impatient, there is also an answer key of sorts.
