WebThe DNA-polymerase can only add nucleotides on an existing strand of DNA, so the primer (located at ori - origin of replication) "fakes" a DNA strand with a couple of RNA nucleotides. It's just to get things going. The primer is always broken down and replaced by DNA at the end of the replication process. WebDuring this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed.
