<prompt> The base sequence of the strand of DNA used as the template for transcription has the base sequence GATCTAC. What is the base sequence of RNA product?CTAGATGGTAGATCGAUCUACGUAGAUC  <response>: Remember when the polarity of given DNA or RNA strand is not given in question always assume it as a 5 - 3 direction according to convention. So the given The DNA template strand is 5 GATCTAC 3. So, the complementary DNA strand will be 3 CTAGATG 5. The sequence of RNA formed will be exactly same to this strand. So Now for RNA, change T to U. So, we get 3 CUAGAUG 5. Now in the options, polarity is not given so assume they are asking you RNA sequence in 5 - 3 direction. Now we have to arrange the RNA sequence from 5 - 3 direction. So the answer is 5 GUAGAUC 3.
