The genetic code is nearly optimal for allowing additional information within protein-coding sequences + Author Affiliations Abstract DNA sequences that code for proteins need to convey, in addition to the protein-coding information, several different signals at the same time. These “parallel codes” include binding sequences for regulatory and structural proteins, signals for splicing, and RNA secondary structure. Here, we show that the universal genetic code can efficiently carry arbitrary parallel codes much better than the vast majority of other possible genetic codes. This property is related to the identity of the stop codons.

Stephen Jay Gould (September 10, 1941 – May 20, 2002) was an American paleontologist, evolutionary biologist, and historian of science. He was also one of the most influential and widely read writers of popular science of his generation. Gould spent most of his career teaching at Harvard University and working at the American Museum of Natural History in New York. In the later years of his life, Gould also taught biology and evolution at New York University. Gould's most significant contribution to evolutionary biology was the theory of punctuated equilibrium, which he developed with Niles Eldredge in 1972. The theory proposes that most evolution is marked by long periods of evolutionary stability, which is punctuated by rare instances of branching evolution. Stephen Jay Gould
Tabela kodonów Fakt, iż kodonów jest więcej niż aminokwasów nazywamy degeneracją kodu genetycznego (kilka kodonów może dyktować ten sam aminokwas). Takie synonimy różnią się między sobą pozycją tolerancji (trzecią pozycją kodonu). Kodon
A sequence alignment, produced by ClustalW, of two humanzinc finger proteins, identified on the left by GenBank accession number. Key: Single letters: amino acids. Red: small, hydrophobic, aromatic, not Y. Blue: acidic. Magenta: basic. Green: hydroxyl, amine, amide, basic. Sequence alignment
Whole-genome dataset for bread wheat now available in Ensembl Plants An improved genome sequence for bread wheat including more than 100,000 genes has been released in Ensembl Plants. Generated under the auspices of the International Wheat Genome Sequencing Consortium (IWGSC), the Chromosome Survey Sequence represents the most complete version of the wheat genome to date.
Format FASTA jest formatem zapisu sekwencji kwasów nukleinowych oraz białek używanym w bioinformatyce. Nukleotydy (dla DNA i RNA) oraz aminokwasy (dla białek) oznaczone są jednoliterowymi skrótami. Format FASTA uwzględnia również możliwość dodawania opisów i komentarzy do sekwencji. FASTA format
