The purpose of transcription is to produce a protein with a  specific function.    DNA is copied into a strand of mRNA and mRNA is read and copied  into a protein to â¦ carry out some function for the cell.    It is the first step in protein synthesis.    /  .2 people found this useful. Because DNA is a much stable molecule than RNA. However, in many viruses genetic information is encoded in their RNA. Consequently, these viruses mutate at a very high r â¦ ate and change constantly to avoid onslaught from the host's immune system.
