<h3>Answer:</h3>

The original DNA sequence will be as given below:

                                      3-- TTG ATG ACG--5

                                                or

                                        5--GCA GTA  GTT--3

<h3>Explanation of answer:</h3>

The DNA sequence of the mRNA is equal to the compulsory base sequence of that RNA.

Only in RNA one nucleotide base is uracil which is present in RNA in place of thymine.

So uracil is compulsory to adenine and guanine to cytosine. while adenine is compulsory  to thymine in DNA sequence.

And the direction will be 3 to 5, as mRNA was written in 5 to 3 direction.
