Exceptions to genetic code
WebApr 6, 2024 · Thus, genetic code has been preserved during evolution and is universal. However, there are a few exceptions like AUA code for methionine in Mitochondria and Isoleucine in Cytoplasm. 2. WebJul 19, 2024 · The exceptions are methionine (AUG) and tryptophan (UGG). The degeneracy is found primarily the third position. Consequently, single nucleotide substitutions at the third position may not lead to a change in the amino acid encoded. These are called silent or synonymous nucleotide substitutions and do not alter the …
