What's the answer to this bio question?

Transcription is the process during which the genetic information is transcribed from DNA into RNA. One of the two DNA strands is used a template for the fabrication of a complementary RNA. The RNA retains all the information of the DNA from which it was copied, as well as the base-pairing properties of the DNA. Transcription is similar to DNA replication in that one of the two DNA strands acts as a template on which the base-pairing abilities of the incoming RNA nucleotide are tested. The RNA nucleotide is only incorporated as a covalently linked unit if a good match with the DNA template is achieved.
