This lesson will be best for students who have studied DNA, transcription, and translation. This lesson models how m-RNA can be translated different forms protein. Familiarity with RNA codon charts is important.
Students take the role of a genetic counselor and determine the possibility that expectant parents will have a child who has sickle cell anemia.
This lesson uses Punnet squares, RNA codons, and principles of dominant and recessive genes.
I created this model so that students would be able to interpret an RNA sequence and determine that a correct gene codes for healthy "Red Blood Cells" while a variant of the gene codes for "Redd Bludd Cellz".
Each parent has two alleles which must be decoded.
Students determine each parents genotype and use a Punnet square to determine possible outcomes for the child.
Students are then asked to write a narrative, explaining the results to parents.
