Protein Synthesis Lab

     To produce protein, first is transcription. RNA polymerase matches reads and copies the DNA code for a protein as a messenger RNA copy. Then in translation, the messenger arrives at the ribosome. Then, the ribosome reads the mRNa three bases at a time and translates DNA language into protein language. The result is a protein! 
      Substitution seemed to have the least effect on the proteins since the protein ended up not changing at all. Deletion seemed to have the greatest effect. The protein became a lot shorter than it was originally, which meant a lot of information was left out. It does matter where the mutation occurs. If it was at the end, the results might have been different and only a small portion would've been left out. 
      I chose to do deletion again but in a different position because it seemed to change the protein the most. I took out one part from the very beginning, and it didn't change much from the first deletion. I feel like if I deleted a portion from the end instead, the results would have been different.
     Mutations affect our life since it could happen to any one of us. Mutations are the reasons for why cancer and other diseases happen. One disease that is caused my mutations is phenylketonuria. Without treatment it causes intellectual disabilities.
