An original dna strand has the following base sequence: taggtaact what base sequence would be produced through transcription

Answer;
AUCCAUUGA
The base sequence that would be produced will be; will be AUCCAUUGA.

Explanation;
Transcription is the process by which RNA are synthesized from DNA molecules, by the enzyme RNA polymerase.
The process takes place in the nucleus of a cell and DNA acts as a primer for the process. 
During the process; the corresponding base pairs are such that; A will correspond to T, while G will correspond to C. However in the RNA the nucleotide base Thyamine is replaced with nucleotide Uracil.

Because it's sugar that us the answer

If the experiment was perfomed more then once and you get the same results
