A-U-G-C-G-U-U-A-G-G-G-A-A-A-U-U-G-A
During transcription, the mRNA strand is synthesized complementary to the DNA template strand. Given the DNA strand "GCA TAG," the corresponding mRNA strand would be "CUG AUC," where each DNA base pairs with its RNA complement (G with C, C with G, A with U, and T with A).
First, you must understand that a strand of mRNA, is the complement of one side (the left) of DNA. Basically, you take the one side of the DNA strand and complement it by using these pairs: Adenine:Uracil, Cytosine:Guanine, Thymine:Adenine. They are all usually abbreviated by their first letter. Second, in order to find the mRNA, you must understand the process of protein synthesis. If you know the process, then it should be clear that the mRNA is made from one side of the DNA strand during the transcription. It then moves out of the cell and into the cytoplasm to start translation.
During transcription, the mRNA strand is synthesized complementary to the DNA template strand. For the DNA strand GCA TTA, the corresponding mRNA would be CGU AAU. This is because adenine (A) pairs with uracil (U) in RNA, while cytosine (C) pairs with guanine (G) and vice versa.

That mRNA sequence had to come from the complement to it. Remeber that the sequence is normally read 5' to 3'. The complement that produced it would be seen in the 3' to 5' orientation (reverse) during transcription. Therefore, find the complement source by reading the sequence in reverse and making the following substitutions: a becomes t, u becomes a, g becomes c, and c becomes g. The result is the following DNA source sequence read 5' to 3': ctaagtcgcaatttttggcat.

The complimentary strand of MRNA would be AAUUCCGG.
mRNA forms a complementary sequence to the DNA it is transcribed from. Therefore, the DNA strand would be the complement (opposite base pair) from what is present in the mRNA. Also, remember that RNA uses uracil (U) in place of thymine (T). For the mRNA strand CUC-AAG-UGC-UUC, the complementary DNA strand would be GAG-TTC-ACG-AAG.
GCT AT
the DNA strand GTT ACC would be transcribed to CAA UGG.

The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.

The DNA strand CAT-TAG would produce a complementary mRNA strand of GUA-AUC.
