Final answer:
The complementary mRNA sequence to the given DNA sequence (TTT GGG CCC ATA) is AAA CCC GGG UAU, which is determined by the base pairing rules of A with U and G with C.
Step-by-step explanation:
The student's question asks for the mRNA sequence that would be complementary to the given DNA sequence (TTT GGG CCC ATA). To find the corresponding mRNA sequence, we must apply the rules of base pairing where adenine (A) pairs with uracil (U) in RNA instead of thymine (T), and cytosine (C) pairs with guanine (G). The DNA sequence (TTT GGG CCC ATA) would be transcribed into mRNA as (AAA CCC GGG UAU).
Thus, the complementary mRNA sequence to the DNA sequence TTT GGG CCC ATA would be:
AAA CCC GGG UAU
This follows the base pairing rules of A with U and G with C in the transcription process from DNA to mRNA.
