Final answer:
The correct DNA and mRNA sequences corresponding to the given tRNA sequence UAC CAC CCC GUA UGG CUG GGA AUA UCG are option (b). The DNA sequence is TAC CAT GGG CAT TGC CTA CCC TTA ATC, and the corresponding mRNA sequence is UAC CAU GGG CAU UGC CUA CCC UUA AUC.
Step-by-step explanation:
The question asks for the corresponding DNA and mRNA sequences given the tRNA sequence UAC CAC CCC GUA UGG CUG GGA AUA UCG. To answer this, we must understand that during the process of protein synthesis, the mRNA is transcribed from the DNA template and then translated into an amino acid sequence by tRNAs. The tRNA anticodons pair with their complementary mRNA codons to add amino acids or terminate translation.
In the given options, the correct DNA and mRNA sequences can be identified by recognizing that DNA pairs adenine (A) with thymine (T) and cytosine (C) with guanine (G), while RNA pairs adenine (A) with uracil (U) and cytosine (C) with guanine (G). However, the tRNA sequence provided is already the anticodon sequence. To find the correct option, we need to match the anticodons to mRNA codons and then derive the DNA template sequence from the mRNA.
The correct answer is option (b), which provides the DNA sequence TAC CAT GGG CAT TGC CTA CCC TTA ATC and the corresponding mRNA sequence UAC CAU GGG CAU UGC CUA CCC UUA AUC. This mRNA sequence matches the given tRNA anticodon sequence perfectly, hence option (b) is the correct answer.
