1.	One of the following is true with respect to AUGA. It codes for methionine onlyB. It is also an initation codenC. It codes for methionine in both prokaryotes and eukaryotesD. All of the above
Answer» Correct Answer - D Polypeptide synthesis is signalled by two initiation codons commonly AUG or methionine codon and rarely GUG or valine codon. Since there are 64 triplet codons and only 20 amino acids, the incorporation of same amino acids must be influenced by more then one codon. Only trytophan (UGG) or methionine (AUG) are specified by single codons. AUG codes for methionine in both prokaryotes and eukaryotes.
