Review Transcription and Translation, Mutations

Students transcribe and translate the following DNA gene...

TATACCCCGGGAAAATT

First into mRNA then into a protein using the following link...
Codon Chart

Then students use paper models to review Transcription and Translation.

Finally we took notes on codon (3 letter mRNA code), anticodon (3 letter tRNA code), and different mutation types (Substitution, Insertion, Deletion, and Transformation)

Examples of those mutations...
Original Strand:
ATTGG
ATCGG: Substitution
ATGG: Deletion
ATTCGG: Insertion
AGGTT: Tranformation

The most harmful mutations are Insertions and Deletions.
