Answer:
DNA sequence 1: TAATGCGTA
DNA sequence 2: GGCTTTACA
DNA sequence 3: CTAGTAATG
DNA sequence 4: AAAAATTGC
Step-by-step explanation:
DNA sequence is complementary to its mRNA. Adenine of mRNA pairs with Thymine (T) of DNA; Uracil (U) of mRNA pairs with Adenine (A) of DNA.
Similarly, Guanine (G) of mRNA pairs with Cytosine (C) of DNA and vice-versa.
a) mRNA sequence 1: AUUACGCAU
DNA sequence 1: TAATGCGTA
b) mRNA sequence 2. CCGAAAUGU
DNA sequence 2: GGCTTTACA
c) mRNA sequence 3. GAUCAUUAC
DNA sequence 3: CTAGTAATG
d) mRNA sequence 4. UUUUUAACG
DNA sequence 4: AAAAATTGC
