Detailed explanation-1: -Answer and Explanation: Because anticodon sequences are complementary to the codons, we will use the complementary base pair rule, where A pairs with U (remember that this is RNA) and C with G. Therefore the anticodon for UUC is AAG, for AUC it is UAG, for CCG it is GGC, and for CGU it is GCA.
Detailed explanation-2: -Since they do not code for any amino acid, they obviously, do not have corresponding tRNA molecules that have the respective anticodons or carry the amino acids. Thus, the corresponding anticodons do not exist.
Detailed explanation-3: -Option D AUG : The anticodon on tRNA of template DNA having AAA will be AAA. AUG is a start codon. The start codon is the first codon of a ribosome-translated transfer RNA (tRNA) transcript.
Detailed explanation-4: -The AUG start codon signals the ribosome to place in the amino acid methionine because the tRNA that has methionine attached to it has the anticodon sequence UAC.
