Codonkäyttöä
Codonkäyttöä, or codon usage, refers to the non-random selection of synonymous codons by an organism. While multiple codons can code for the same amino acid, different organisms, and even different genes within the same organism, tend to favor certain codons over others. This preference is not due to any difference in the amino acid they encode but rather reflects the relative abundance of different transfer RNA (tRNA) molecules available within the cell. Organisms often have a higher concentration of tRNAs that recognize the more frequently used codons, leading to more efficient and accurate protein synthesis.
The pattern of codon usage can be influenced by several factors. The most significant is the GC
