D

Verified step by step guidance1
Understand the process of transcription: it is the synthesis of RNA from a DNA template.
Recall that RNA polymerase reads one strand of the DNA to create a complementary RNA strand.
Identify that the strand used by RNA polymerase is called the DNA template strand, which is complementary to the RNA being synthesized.
Recognize that RNA primers are involved in DNA replication, not transcription, so they are not the template for RNA synthesis.
Conclude that the RNA strand is synthesized by making a complementary copy of the DNA template strand of a gene.
