During , dna serves as a template to assemble a strand of rna.

During TRANSCRIPTION, DNA serves as a template to assemble a strand of RNA. Transcription is the very first stage in the process of gene expression. During transcription, genetic information from a specific DNA is copied into RNA, thus the DNA is serving as template. The enzyme that catalyses the reaction is RNA polymerase. The transcribed RNA is used by the cells to synthesize proteins.
