    Let me know if this looks correct. Also, I think you needed Start and Stop codons as well. Check with the professor.
    Thanks!

    1. Hi sorry I posted the wrong strand! The correct DNA strand is as follows.

    2. Hello Alfa

      The first time that I submitted my code it was incorrect. I had the start codon and forgot the stop codon. My first DNA strand was wrongfully reverse-transcribed.

      This was my first attempt to try to reverse-transcribe into DNA.

      When I figured out that I wrongfully transcribe the A and the T and the U and the T, I found my problem. After my classmate posted what she thought my original DNA strand said, I took a close look at my strand. I notice the mistakes and placed the correct DNA strand that I should have had and in the mix up, I forgot to add the stop codon.

      This is what it should look like, my DNA strand with the proper T’s in place and the U’s transcribe for the correct base A.

      My sentence said, “Natural selection is good for the animals to adapt.”

  2. Alfa, you and I came up similar codes. Not sure why we have differences but you can compare your decode with mine for reference (below).

    Fitness, While I appreciate the updated code, it's a little late for Alfa to return to try another decode. It would have been better to acknowledge the errors she points out and then correct the original code instead of providing a new one.

    In the original code, you were missing the very important start/stop codons, as alfa pointed out, so your decoder didn't know where to start the translation process.

    In the new code, which is better, you have included a start codon but you are still missing a stop codon and you are also missing the random bases at the beginning and end that would make your decoder look for those start/stop codons. In real DNA, a gene is sandwiched in between junk code and the enzyme that runs the translation process has to look for the start and stop codons to know where to begin and end.

    Original:
    DNA: ATGGGGCTTGCCTTCTGGAATTTGCGG
    RNA/Codons: UAC CCC GAA CGG AAG ACC UUA AAC GCC
    From want hungry adapt fossil monster because anthropology good.


    New:
    DNA:TACCCCGAACGGAAGACCTTAAACGCC
    AUG GGG CUU GCC UUC UGG AAU UUG CGG
    (start) Natural selection is good for the animals to adapt.

    If you have questions on this, check out some other student codes, making sure to read the comments to see if and where errors were made. You can also email me for clarification.
