Murakami and M. Sisido extended some codons to have four and five bases.
This passage simply does not correspond to the true state of affairs,because 50% codons omonimičny.
On the other hand,redundant different codons, denoting the same amino acids, has long been considered as synonymous.
By 1966, Nirenberg announced that he had deciphered the sixty-four RNA codons for all twenty amino acids.
While not rare,a frequently used codons do not affect this process, When were introduced after codon 223 or 307.
Since there are 4 bases in 3-letter combinations,there are 64 possible codons 43 combinations.
The genetic code consists of three-letter'words' called codons formed from a sequence of three nucleotides e.g. ACT, CAG, TTT.

Since only 20 amino acids are used, multiple codons code for the same amino acids.
Alternate start codons are still translated as Met when they are at the start of a protein even if the codon encodes a different amino acid otherwise.
Let's Say, in the proposal it is necessary to choose one of two words unique codons with dubletami-homonymous.
Thus, dubletno-tripletnye if you count the codons"words", the code itself is, among other things, two-dimensional, the omonimo-synonymous.
The code defines a mapping between tri-nucleotide sequences,called codons, and amino acids.
But even rarely encountered homonymous codons, If not correctly reading, will give errors in protein synthesis, that is unacceptable for the body.
I see, that such shifts framework read the mRNA of pure physics and chemistry neob″âsnit′,as well as contextual distant influences and"reinvention" codons.

Amino acids with similar physical properties also tend to have similar codons, reducing the problems caused by point mutations and mistranslations.
Thanks to FA there is a short delay between pairing codons with antikodonom and elongation of the peptide, that allows you to separate itself from tRNA the Ribosome.
Moreover, it without any reason considered,that such strange codons are rarely found in the genome of Biochemistry, and that is why they are not dangerous.
