not much likely. It seems, that at START codon the wobling takes place on first position :lol:

Cis or trans? That's what matters.

Actually, it appears that it can, but mainly* in the mitochondria of some Eukaryotes (for example in vertebrates). Take a look through this, as it lists the standard genetic code and then many, if not all, alternative genetic codes and where they are found. Any codon with an "i" next to it can be a start codon in that situation:

NB: the code tables give the DNA codes rather than the RNA codes, so obviously it shows T instead of U. :)

*I say "mainly" because I didn't examine all of them... it may be "only" rather than "mainly"

thanx, :D ,yes,it seems when comes to genome encoding proteins.
