Transcription is the process of copying genetic information from one strand of the DNA into RNA. In transcription, only a segment of DNA or only one out of the two stands is copied into RNA. Unlike replication, which once set in, the total length of DNA of organisms gets duplicated.

Transcription is the first step in gene expression. It involvescopying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
