It can also be represented in a DNA codon table. The DNA codons in such tables occur on the sense DNA strand and are arranged in a 5 ′-to-3 ′ direction. Different tables with alternate codons are used depending on the source of the genetic code, such as from a cell nucleus, mitochondrion, plastid, or hydrogenosome. [5]
Four novel alternative genetic codes were discovered in bacterial genomes by Shulgina and Eddy using their codon assignment software Codetta, and validated by analysis of tRNA anticodons and identity elements; [3] these codes are not currently adopted at NCBI, but are numbered here 34-37, and specified in the table below. The standard code; The ...
The two other start codons listed by table 1 (GTG and TTG) are rare in eukaryotes. [3] Prokaryotes have less strigent start codon requirements; they are described by NCBI table 11 . B ^ ^ ^ The historical basis for designating the stop codons as amber, ochre and opal is described in an autobiography by Sydney Brenner [ 4 ] and in a historical ...
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets or codons) into proteins. Translation is accomplished by the ribosome , which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA ...
The bacterial, archaeal and plant plastid code (translation table 11) is the DNA code used by bacteria, archaea, prokaryotic viruses and chloroplast proteins. It is essentially the same as the standard code , however there are some variations in alternative start codons .
We derive an information-rich, alternative representation of the genetic code table. The new organization of the 64 codons is circular with an asymmetric distribution of codons that leads to a clear segregation between GC-rich 4-codon boxes and AU-rich 2:2-codon and 3:1-codon boxes. [16]
This is the standard genetic code (NCBI table 1), in amino acid→codon form. By default it is the DNA code; for the RNA code (using Uracil rather than Thymine), add template parameter "T=U". Also listed are the compressed codon forme, using IUPAC nucleic acid notation.
The mold, protozoan, and coelenterate mitochondrial code and the mycoplasma/spiroplasma code (translation table 4) is the genetic code used by various organisms, in some cases with slight variations, notably the use of UGA as a tryptophan codon rather than a stop codon.
