Answer: The mRNA sequence is CGUAGGCU
The sequence of DNA molecule is GCATCCGA and when it is transcribed, it forms mRNA ( messenger RNA). The mRNA sequence is complementary to the DNA template. The corresponding nucleotides in mRNA are added in the following manner-
For G in the DNA, C ( cytosine) is added in mRNA and vice versa. Similarly, for A ( adenine) , U ( Uracil) is added in mRNA and for T( thymine), A ( adenine) is added in mRNA.
Thus, for the given DNA sequence, CGUAGGCU is the right mRNA sequence.
