(C) The genetic code is generally considered universal,meaning it is the same in most organisms. However,there are exceptions to this universality.In human mitochondria $(mtDNA)$,the genetic code differs from the standard nuclear genetic code.For example,the codons $AGG$ and $AGA$ normally code for arginine,but they function as stop signals in human mitochondria.Additionally,the codon $UGA$,which is a standard termination codon,codes for tryptophan in mitochondria,and the codon $AUA$,which normally codes for isoleucine,codes for methionine in human mitochondria.
