DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand.
Transcription is the process by which an RNA polymerase uses DNA as a template to make RNA. This produces a single stranded product that spans only a tiny fraction of an entire DNA molecule. Also, RNA polymerases are slightly more error-prone than DNA polymerases.
