    The start and end codon need to be switched, they are on the wrong sides.
    Im not sure where the error is because the whole sentence did not make sense. For example, you ended the code with "because".

    1. Kait, can you include the sentence that you did decode, even if it didn't make sense?

    3. stop- for dream proteins study time bad pizza because- start

  2. the start and end decode is probably incorrect but I cannot figure out if the rest of the sentence is. It is suppose to say: Anthropology is the study of us and animals....the start codon is suppose to be: ATT

  3. Kait, I understand the errors, but it would have been helpful to provide the decode that you came up with. This might have guided R AMIN to figure out where they went wrong.

    R AMIN,

    You can't pick your own start codon. You have to use the one identified on the codon sheet in the assignment instructions (AUG). That is the only way your decoders can know where to start. Same thing with the stop codon. You need to use UAG from the codon sheet.

    Without the correct start codon, your decoder just has to start from the beginning, which produces a nonsense sentence. Here is my decode for reference:

    DNA: ATCAAGGTTTCCGGCTATCGTTGAAATTAC
    RNA: UAG UUC CAA AGG CCG UAU GCA ACU UUA AUG
    (stop) For dream proteins study of bad pizza because (start)

    Given the sentence you said you wanted to code, this is the process that you should have completed:

    Anthropology is the study of us and animals.
    Reverse translation: AAC CUU UGG CCG UAU GCU UCA AAU
    Add start/stop codon: AUG AAC CUU UGG CCG UAU GCU UCA AAU UAG
    Remove spaces: AUGAACCUUUGGCCGUAUGCUUCAAAUUAG
    Reverse transcription: TACTTGGAAACCGGCATACGAAGTTTAATC
    Add some random bases: ATTGTACTTGGAAACCGGCATACGAAGTTTAATCATAG
    (This last line is what you were to post for this assignment.)
