Which of the following best describes the primary function of RNA polymerase in eukaryotic cells?

Genomic DNA from a mouse is isolated, fragmented, and denatured into single strands. It is then mixed with mRNA isolated from the cytoplasm of mouse cells. The image represents an electron micrograph result showing the hybridization of single-stranded DNA and mRNA.

What term best identifies the nucleic acid region indicated by the 'd' pointer?
