Did I do these complementary strands correctly

1. Complete the DNA molecule by writing a complementary strand.

Coding Strand: CGT CTC TTC GGA CAC
Complementary Strand: ______________________

My answer: GCA GAG AAG CCT GTG

2. Write the mRNA sequence that will be created in the process of transcription. The DNA coding strand has the information for the gene, so the strand must be transcribed. The relationships are slightly different for RNA, because RNA does not have T; therefore, U should be substituted for T. To transcribe DNA to RNA, the pairing relationship is A – U, T – A, C – G, and G – C, respectively.

Coding Strand: CGT CTC TTC GGA CAC
mRNA Strand: _____________________

My Answer: GCA GAG AAG CCU GUG

No.
You neglected directionality in every case.

Coding Strand: CGT CTC TTC GGA CAC
Complementary Strand: 3'-GCA GAG AAG CCT GTG-5'

See the 3' and 5'? If you don't know what those are, kick your teacher, hard.

Question #2 is BAD. Kick your teacher AGAIN. The coding strand has the SAME directionality and sequence as the RNA (using the definition from Wikipedia of "coding strand.")

Coding Strand: CGT CTC TTC GGA CAC
mRNA Strand: 5'-CGU CUC UUC GGA CAC-3'

==============

Ask your teacher to reduce confusion by marking the 5' and 3' ends in every case. Science is about reducing confusion, not increasing it. DNA has directionality and it is important.

Yes, nice work :)

Looks right to me.

That's right. You seem to understand this very well.
