For example, if there were two bases per codon, then only 16 amino acids could be coded for (4²=16). Because at least 21 codes are required (20 amino acids plus stop) and the next largest number of bases is three, then 4³ gives 64 possible codons, meaning that some degeneracy must exist.
However, it is now agreed that the genetic code evolves, [22] resulting in discrepancies in how a codon is translated depending on the genetic source. [21] [22] For example, in 1981, it was discovered that the use of codons AUA, UGA, AGA and AGG by the coding system in mammalian mitochondria differed from the universal code. [21]
This is a list of disorder codes in the Online Mendelian Inheritance in Man (OMIM) database. These are diseases that can be inherited via a Mendelian genetic mechanism. OMIM is one of the databases housed in the U.S. National Center for Biotechnology Information. Isolated 17,20-lyase deficiency; 202110; CYP17A1
This article is missing information about The NCBI gc.prt data format, though we could need to wait for an upstream doc fix. Please expand the article to include this information. Further details may exist on the talk page .
The code emerges at a transition when the mapping of codons to amino acids becomes nonrandom. The code's emergence is governed by the topology defined by the probable errors and is related to the map coloring problem.

Examples of degeneracy are found in the genetic code, when many different nucleotide sequences encode the same polypeptide; in protein folding, when different polypeptides fold to be structurally and functionally equivalent; in protein functions, when overlapping binding functions and similar catalytic specificities are observed; in metabolism, when multiple, parallel biosynthetic and ...

The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...
