Genetic Chart Worksheet Complete the following chart using your genetic code chart worksheet: a. Complete the mRNA codon column by writing the correct mRNA codon for each DNA base sequence given b. Identify the process responsible for part A. by writing its name under the process column c. Write the correct tRNA anticodon that binds to each mRNA codon. d. Identify the process responsible for part C. by writing its name under the second process column e. Using your genetic code chart, identify the name of the correct amino acid that is coded by each mRNA base sequence DNA Base Sequence Process: ____________ mRNA codon Process: ___________ tRNA codon Amino Acid: Process: ____________ mRNA codon Process: ___________ tRNA codon Amino Acid: Process: ____________ mRNA codon Process: ___________ tRNA codon Amino Acid: CCC TAT GAG GCG AAC DNA Base Sequence TTG CTC GGA TTT CGC DNA Base Sequence AGG CCA TGG GCT TCT DNA Base Sequence Process: ____________ mRNA codon Process: ___________ tRNA codon Amino Acid: ACT GCT TTG CAG TAG Mutations Multiple Choice Questions: 1.
