[Puzzle] JayNineteen Youtube Profile Update [5/7/07]

...
When translated this gives us VTVTER, which still looks like nonsense to me, I have no clue how we would apply it or what we would apply it to.
...

The only sure letters (within this unproven theory) are the 2 T's. All the others have some wiggle room as I showed in my previous post with the question marks. I would guess that once we get a solid result it would most likely be applied as Jay's last name on his myspace.

[deagol]

Result = UZQDFJ

UZQDFJ if I include the Met for the first shift, ignoring the last (Tryptophan).

Actually that should be UZGDFO if you do the looperama trick on the 8th letter for Proline and Serine.

Here's another possibility:

Isoleucine or Arginine

4(+13) 1(+4) 8(+17) 4(-11) 1(-14) 8(-16)

NTRAMS or NTRAMO

[ShardinsKitten]

NTRAMO = Matron
NTRAMS = doesn't make any 6 letter words

dunno if that's where you're supposed to go from there but *Shrugs* all I got. lol

[Luminous]

This is some amazing, mad decoding, that, try as I might, goes way over my head

Makes me wonder if there is an easier way to approach this. Something we're overlooking?

Seems like the problem is that the frequency of the phrase/key don't match to produce a sequence of codons - hope this analysis is correct.

This makes me wonder - If Jay wanted to mask the frequency in order to make things more challenging to decode, what kind of strategies might he use? Sorry I don't have any answer for this - I'm better at coming up with questions lol

[deagol]

Lum, the tough part is coming up with the right questions, and yours are always insightful.

What do you mean by frequency?

[Luminous]

I don't know if frequency is the right word.

I'm not sure how to describe what I mean. But there is a way you and Mouse break down a cipher to look at all the possible results you can achieve. I think I've heard you say you "force it".

What I'm thinking is, if Jay wanted to create a cipher text that couldn't be forced - or at least would be difficult to force - what kind of strategies might he use?

Hope this makes sense.

[ignatzmouse]

Unfortunately there's a really easy one: one-time pad. Encrypt anything with a random enough sequence of the same length, and ta-da perfect encryption. We're working on the hope that a) the plaintext is a DNA sequence, and b) the key isn't random.

Running out of options though...

[Musique]

Have any of you tried contacting Jay for some input?

[ignatzmouse]

Hmm, and I tried Vigenering to see which keys would decrypt/encrypt the beginning of the message to "ATG" (start) and the end to "TAA", "TAG" or "TGA" (stop). All gibberish. Ditto with U replacing T.

If it were a one time pad though, it seems like he would find a way to provide the key. In the past the key has always been provided. I can't imagine we would be expected to guess it - at least I would hope not

Indeed. As TOSG said, we're missing something.

[ignatzmouse]

Here's what I was saying about the wiggle room:

Code: Select all

  atg g** ccg g*t aca **g ttt ***
          cct t*t         ttg
                          tgt
                          tgg

 skip  ?   T   ?   T   ?   ?

If anyone understands this, can you fill-in the question marks? Ignatz?

You rang? Doing the exhaustive search on the possible values for * we get:

Code: Select all

AGNPV
T
TRX
T
BEFHMSXY
ORV

Pick one letter from each row to make a word. This is pretty unlikely: the second T means the first letter must be A. and I don't think there are any words starting "ATTT", "ATRT" or "ATXT".

[TOSG]

Interesting analysis. But in the past, our translated DNA sequences have never been bookended by start and stop codons. Although that WOULD explain the difference in the number of code letters and the number of bases that we can decode with the provided decoding numbers.

Like Musique said, although Jay hasn't logged into youtube in a few days, it might not be a bad idea to shoot him a message.

The volunteer corps has been going crazy over your profile.
Going crazy, I say crazeeeee!
All attempts at decryption have gone nowhere.
Can you give us a hint?
?

Lame "TGAC?" meaning give us a hint whether it's an encrypted DNA sequence we're looking for. We shall see if we get a reply.
