Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the DNA sequence is ATC, what would be the anticodon that would carry the correct amino acid?
A
TAG
B
UAG
C
AUC
D
ATC
Explanation: 

Detailed explanation-1: -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: -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-3: -Answer and Explanation: Using the base-pairing rules, we can generate the complementary sequence to UAC as AUG. Since the question indicates the direction of the nucleic acid as 5’ to 3’, the complementary sequence is the opposite direction (3’ to 5’). Therefore the correct answer is 3’AUG 5’, which is in option (e).
