Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

G C
For this reason:
<em>DNA:</em><em> 3’ A G G T C T T C A C 5’</em>
<em>mRNA:</em><em> 5'-U C C A G A A G U G-3'</em>
