Question

In this depiction of transcription, the __________ strand is __________ because it __________.
A)upper; RNA; is single-stranded. 
B)lower; RNA; contains uracil.
C)lower; RNA; contains thymine.
D)upper; RNA; has no uracil (U).
E)lower; DNA; contains adenine (

Quizplus · Accepted Answer

The depicted strand is DNA, specifically the template strand since RNA polymerase is binding to it and synthesizing an RNA strand complementary to it. RNA contains uracil instead of thymine, so the RNA strand being synthesized will have uracil in place of thymine. Therefore, the lower DNA strand (template strand) is RNA because the RNA being synthesized will contain uracil.
