Question
Using the genetic code table, write out a mRNA sequence that could be used as a code to make the following protein:
Met - Pro - Arg
Solution
To write out an mRNA sequence that codes for the protein sequence Methionine (Met) - Proline (Pro) - Arginine (Arg), you would first need to refer to a genetic code table. This table shows the mRNA codons that correspond to each amino acid.
- Methionine (Met) is coded by the mRNA codon AUG.
- Proline (Pro) is coded by several mRNA codons, including CCU, CCC, CCA, and CCG. We can choose any of these, but for simplicity, let's choose CCU.
- Arginine (Arg) is also coded by several mRNA codons, including CGU, CGC, CGA, CGG, AGA, and AGG. Again, we can choose any of these, but let's choose CGU for simplicity.
So, an mRNA sequence that codes for the protein sequence Met - Pro - Arg could be AUG - CCU - CGU.
