Presentation Transcript

  1. Function finders blast Discover how DNA sequences code for proteins with different roles and functions

  2. Function finders activity • Translate the DNA code into an amino acid sequence using the codon wheel • Use the amino acid sequence to discover the proteins name and function using a BLAST search

  3. The codon wheel • Start from the centre and move outwardsExample: CAT = H (Histidine)

  4. The codon wheeL • Translate the following:atg gag gag ccg cag tca gat cctagcgtc gag ccg D M P Q S P S V E P E E
