Talk:Expanded genetic code

Untitled

I have copied part of this into genetic code so this atm is repeated. but I will expand on it soon. so plz do not delete. --Squidonius (talk) 21:14, 13 October 2009 (UTC)

Removed for lack of clarity

Removed "from the existing 20 to a theoretically possible 172," because it is not clear what the 20 refers to (though it probably means the 20 amino acids expressed by the standard code) or where the theoretically possible 172 comes from. If the same redundancy as the current codes were used an expansion of about a factor of four might be expected, for example. It is probable that the 172 is based on expanding the existing 64 codes to 216 giving an additional 152 codes, which if they were mapped uniquely to new AAs would yield a total of 172 AAs. It is not clear, however, with the massive re-engineering of the transcription machinery required, why the redundancy in the existing code need be preserved, nor indeed the coding length of 3.

Query

First, a thanks. I created this page over five years ago, but I haven't touched it since. I am glad it is in a good shape and bold edits are contested. Today, I was hoping to give it focus and update it with recent literature (in procrastination from writing a grant), but got stopped midway. I promise I'll do it soon. I was partially surprised that my edit got reverted. In it's current form it has a repetition (there are 20 amino acids) and lacks a summary of the how it is done conceptually and what the articles covers, so I will fix it. I will add reference, but I was hoping to build on my previous edit. I assume it wasn't a needs references issue, right? Two issues I see that are problematic are (i) choice of the usage of terms standard and nonstandard, and (ii) the claim that UAG recoding is the most prominent. --Squidonius (talk) 05:12, 2 February 2015 (UTC)
