In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.
Jobisdone [24]

Answer: d). UAG

Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.

From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
