Protein Synthesis Practice
Molecules of DNA carry the genetic instructions for protein formation. Converting these DNA
instructions into proteins requires a series of coordinated steps in transcription and
translation.
Complete the following table.
1. Complete column B by writing the correct mRNA codon for each sequence of DNA bases listed in the
column marked DNA Base Sequence. Use the letters A, U, C or G.
2. Identify the process responsible by writing its name in the process box in column A.
3. Complete column D by writing the correct anticodon that binds to each codon from column B.
4. Identify the process responsible by writing its name in the process box in column C.
5. Complete column E by writing the name of the correct amino acid that is coded by each base
sequence. Use a codon chart to translate the mRNA base sequences to amino acids.
