Construction of code map

Part of Lesson Plan: Mapping Central Dogma

Activity Overview / Details

Students will locate and use existing genetic code maps to translate mRNA sequences generated by the teacher.  Start a sequence with start codon (AUG) include several amino acid codons and then finish with a stop codon (UAA, UAG, or UGA).  For example:

AUG-CUU-UGG-ACG-UAG

Or start with the gene and have them generate the mRNA above before translating their sequence:

TAC-GAA-ACC-TGC-ATC

After this exercise they will generate their own map initially in a sketch form with pencil and paper. The teacher has the option here to restrict the activity physical maps or something digital that can displayed online using Flash or other software.

After contructing their map they should have other student groups check for accuracy.

See attached student generated code map.
