I examine all the coding sequences in Diceros bicornis (Black rhinoceros) and identify each codon that translates into threonine with the following results: 25% ACA, 25% ACC, 25% ACT, 25% ACG. This results supports the conclusion that there is no codon usage bias.
- The term "codon use bias" describes variations in the frequency at which synonymous codons appear in coding DNA.
- A codon is a group of three nucleotides that codes either the end of translation or a particular amino acid residue in a polypeptide chain.
- The occurrence of specific codons being used more frequently than other synonymous codons during the translation of genes is known as codon use bias, and its severity varies between and within species.
- here, each codon translating into threonine is in equal proportion ie, 25%.
- 25% ACA, 25% ACC, 25% ACT, 25% ACG indicate that the codons are used in equal proportion and thus there is no codon usage bias in Diceros bicornis.
