Question

The triplet base sequence in DNA that is translated into a stop codon, whose corresponding tRNA anticodon, is AUU is given by :

Answer 1

TAA

Step-by-step explanation:

The triplet base sequence in DNA that is translated into a stop codon, whose corresponding tRNA anticodon, is AUU is given by TAA.

There are three stop codons in nature and these include UAG, UGA, and UAA. Out of all these codons, the one whose corresponding tRNA codon is AUU would be UAA stop codon.

However, as a rule of thumb, only RNA contains uracil base instead of thymine in DNA. Hence the 'U' in UAA mRNA stop codon which refers to uracil is replaced by 'T' (thymine) in DNA.

Therefore, UAA becomes TAA.
