Hello Dr. Rodriguez and classmates:

My DNA is:

ABA-TAA-GGA-TGG-ATG-GCA-AAC-GTC-TGA-ACG-TGC-LER

I believe it can be easily transcribed into mRNA.

  1. If i got this right and i hope i did lol, i got.

    "Students Become Monster(s) From lean(ing) To Eat Pizza After School."

    And yes eating way to much of this after school can make someone into a food monster lol. :)

    1. Thank you Myles. You are, of course, on the money. Wasn't that a fun assignment? Good job!

  4. Myles, decoded correctly, but did you see any errors in the code that you could critique? This is a teaching moment for everyone. What guidance could you offer?

    Debra, a couple of things:

    - The random bases had to be actual bases (ATCG). No other letters from the alphabet qualify.
    - You broke the DNA into triplets, which made the sentence too easy to figure out. Real DNA molecules don't have hyphens. :-)
    - You were missing start and stop codons, so decoders wouldn't have known where to start the decode, without the hyphens, of course. So if you do a straight decode, you end up with a nonsense sentence. I've provided that straight decode for you below to see the problem, using question marks where standard bases were missing in the DNA:

    DNA: ABATAAGGATGGATGGCAAACGTCTGAACGTGCLER
    RNA: U?UAUUCCUACCUACCGUUUGCAGACUUGCACG???
    Triplets UAU UCC UAC CUA CCG UUU GCA GAC UUG CAC G
    Of into from was study in bad unusual to think G

    Here is what your DNA code process should have looked like:

    Sentence: Students become monster(s) from learn(ing) to eat pizza after.
    RNA triplets: AUU CCU ACC UAC CGU UUG CAG ACU UGC
    Add start/stop codons: AUG AUU CCU ACC UAC CGU UUG CAG ACU UGC UAG
    Take away spaces: AUGAUUCCUACCUACCGUUUGCAGACUUGCUAG
    Convert to DNA: TACTAAGGATGGATGGCAAACGTCTGAACGATC
    Add random bases: CGTTCTACTAAGGATGGATGGCAAACGTCTGAACGATCGTGGG

    That last line (with your own choice of random bases) is what should have been posted.

    1. Thank you for the insight, Professor. I appreciate your explanation.
