Question

For the following DNA sequence:

TAC GTT CAG AAG CTT GCT ACG CGC AAT CGA TGT TAA

(a) Write the corresponding mRNA codons.

(b) Write the corresponding t-RNA anti-codons.

Answer 1

To answer the student's question, the corresponding mRNA codons for the given DNA sequence are determined by transcription, with the tRNA anti-codons being complementary to these mRNA codons.

Step-by-step explanation:

The student asks about the transcription and translation of a given DNA sequence into mRNA codons and corresponding tRNA anti-codons. To answer this:

1. To find the corresponding mRNA codons, we transcribe the DNA sequence by replacing thymine (T) with uracil (U) and forming the complementary strand. For example, the DNA sequence TAC would transcribe to the mRNA codon AUG.
2. The corresponding tRNA anti-codons are complementary to the mRNA codons, for example, the mRNA codon AUG would have a tRNA anti-codon UAC.

Therefore, the mRNA codons for the given DNA sequence TAC GTT CAG AAG CTT GCT ACG CGC AAT CGA TGT TAA are:

AUG CAA GUC UUC GAA CGA UGC GCG UUA GCU ACA AUU

And the tRNA anti-codons are:

UAC GUU CAG AAG CUU GCU ACG CGC AAU CGU UGA UAA
