Final answer:
The anticodon to the DNA sequence CTG ACG TTA is GAC UGC AAU, which corresponds to option A. Anticodons are complementary to mRNA codons and are found on tRNA.
Step-by-step explanation:
The correct anticodon to the DNA sequence CTG ACG TTA is option A, which is GAC UGC AAU. During transcription, the DNA sequence is used to create a complementary mRNA sequence. However, anticodons are found on tRNA and are complementary to the mRNA codons, not directly to DNA. Since the DNA sequence provided is likely representing the coding strand, we must first find the complementary mRNA and then the tRNA anticodon.
In this case, the mRNA sequence that would be transcribed from the given DNA sequence would be GAC UGC AAU. Therefore, the anticodon, which is complementary to this mRNA sequence, would be precisely the same as the mRNA sequence itself, as tRNA anticodons are designed to pair with mRNA codons. It is important to remember that in RNA, uracil (U) is used instead of thymine (T)
