Degeneracy of the genetic code is the property of the genetic code in which one amino acid can correspond to several different codons, which makes it more flexible and allows you to encode a larger number of amino acids. For example, the amino acid glycine can be encoded by three different codons: UGA, UAA and UAG. This allows the same gene to be used to encode different proteins, which is important for the evolution and adaptation of organisms to changing environmental conditions.
The degeneracy of the genetic code can be due to several factors. First, this is because different amino acids have different lengths and shapes, making it difficult to code them precisely using a single codon. Secondly, this may be due to the need to use different codons to encode different types of amino acids, such as polar and non-polar, hydrophobic and hydrophilic, acidic and basic. This may also be due to the need to encode various functional groups of amino acids, such as amino groups, carboxyl groups, etc.
However, the degeneracy of the genetic code can also lead to translation errors, where a codon corresponding to one amino acid may be read as a codon corresponding to another amino acid. This can lead to changes in protein structure and function, which can be dangerous for the body. Therefore, in the process of evolution, organisms have developed mechanisms that allow them to correct such errors, for example, by using special enzymes that can correct translation errors.
In general, the degeneracy of the genetic code is an important property of the genetic code and plays an important role in the evolution of organisms and their adaptation to changing environmental conditions.
Degenerate genetic code Degenerate genetic code is a property of the genetic code of living organisms, which means that 1 amino acid (monomer) can be encoded not by one, but by several codons. This phenomenon is known as code degeneracy (or ambiguity).
